Since I don't know Pandas, I will need a month at least to understand
these 2 lines of code. Thanks again.


   Here's a technique to better understand such code:

   Transform it into a program with small statements and small
   expressions with no more than one call per statement if possible.
   (After each litte change check that the output stays the same.)

import pandas as pd

# Warning! Will overwrite the file 'file_20240412201813_tmp_DML.csv'!
with open( 'file_20240412201813_tmp_DML.csv', 'w' )as out:
 print( '''obj,foo1,foo2,foo3,foo4,foo5,foo6
foo1,aa,ab,zz,ad,ae,af
foo2,ba,bb,bc,bd,zz,bf
foo3,ca,zz,cc,cd,ce,zz
foo4,da,db,dc,dd,de,df
foo5,ea,eb,ec,zz,ee,ef
foo6,fa,fb,fc,fd,fe,ff''', file=out )
# Note the "index_col=0" below, which is important here!
df = pd.read_csv( 'file_20240412201813_tmp_DML.csv', index_col=0 )

selection = df.where( df == 'zz' )
selection_stack = selection.stack()
df = selection_stack.reset_index()
df0 = df.iloc[ :, 0 ]
df1 = df.iloc[ :, 1 ]
z = zip( df0, df1 )
l = list( z )
result ={ 'zz': l }
print( result )

   I suggest to next insert print statements to print each intermediate
   value:

# Note the "index_col=0" below, which is important here!
df = pd.read_csv( 'file_20240412201813_tmp_DML.csv', index_col=0 )
print( 'df = \n', type( df ), ':\n"', df, '"\n' )

selection = df.where( df == 'zz' )
print( "result of where( df == 'zz' ) = \n", type( selection ), ':\n"',
   selection, '"\n' )

selection_stack = selection.stack()
print( 'result of stack() = \n', type( selection_stack ), ':\n"',
   selection_stack, '"\n' )

df = selection_stack.reset_index()
print( 'result of reset_index() = \n', type( df ), ':\n"', df, '"\n' )

df0 = df.iloc[ :, 0 ]
print( 'value of .iloc[ :, 0 ]= \n', type( df0 ), ':\n"', df0, '"\n' )

df1 = df.iloc[ :, 1 ]
print( 'value of .iloc[ :, 1 ] = \n', type( df1 ), ':\n"', df1, '"\n' )

z = zip( df0, df1 )
print( 'result of zip( df0, df1 )= \n', type( z ), ':\n"', z, '"\n' )

l = list( z )
print( 'result of list( z )= \n', type( l ), ':\n"', l, '"\n' )

result ={ 'zz': l }
print( "value of { 'zz': l }= \n", type( result ), ':\n"',
   result, '"\n' )

print( result )

   Now you can see what each single step does!

df =
   :
"  foo1 foo2 foo3 foo4 foo5 foo6
obj
foo1   aa   ab   zz   ad   ae   af

result of where( df == 'zz' ) =

foo1  NaN  NaN   zz  NaN  NaN  NaN
foo2  NaN  NaN  NaN  NaN   zz  NaN
foo3  NaN   zz  NaN  NaN  NaN   zz
foo4  NaN  NaN  NaN  NaN  NaN  NaN
foo5  NaN  NaN  NaN   zz  NaN  NaN
foo6  NaN  NaN  NaN  NaN  NaN  NaN "

result of stack() =
   :
" obj
foo1  foo3zz
foo2  foo5zz
foo3  foo2zz
   foo6zz
foo5  foo4zz
dtype: object "

result of reset_index() =
   :
" obj level_1   0
0  foo1foo3  zz
1  foo2foo5  zz
2  foo3foo2  zz
3  foo3foo6  zz
4  foo5foo4  zz "

value of .iloc[ :, 0 ]=
   :
" 0foo1
1foo2
2foo3
3foo3
4foo5
Name: obj, dtype: object "

value of .iloc[ :, 1 ] =
   :
" 0foo3
1foo5
2foo2
3foo6
4foo4
Name: level_1, dtype: object "

result of zip( df0, df1 )=
   :
" "

result of list( z )=
   :
" [('foo1', 'foo3'), ('foo2', 'foo5'), ('foo3', 'foo2'), ('foo3', 'foo6'), ('foo5', 
'foo4')]"

value of { 'zz': l }=
   :
" {'zz': [('foo1', 'foo3'), ('foo2', 'foo5'), ('foo3', 'foo2'), ('foo3', 'foo6'), 
('foo5', 'foo4')]}"

{'zz': [('foo1', 'foo3'), ('foo2', 'foo5'), ('foo3', 'foo2'), ('foo3', 'foo6'), 
('foo5', 'foo4')]}

   The script reads a CSV file and stores the data in a Pandas
   DataFrame object named "df". The "index_col=0" parameter tells
   Pandas to use the first column as the index for the DataFrame,
   which is kinda like column headers.

   The "where" creates a new DataFrame selection that contains
   the same data as df, but with all values replaced by NaN (Not
   a Number) except for the values that are equal to 'zz'.

   "stack" returns a Series with a multi-level index created
   by pivoting the columns. Here it gives a Series with the
   row-col-addresses of a all the non-NaN values. The general
   meaning of "stack" might be the most complex operation of
   this script. It's explained in the pandas manual (see there).

   "reset_index" then just transforms this Series back into a
   DataFrame, and ".iloc[ :, 0 ]" and ".iloc[ :, 1 ]" are the
   first and second column, respectively, of that DataFrame. These
   then are zipped to get the desired form as a list of pairs.



And this is a technique very similar to reverse engineering. Thanks for
the explanation and examples. All this is really clear and I was able to
follow

help: pandas and 2d table

[jak via Python-list]

Hi everyone.
I state that I don't know anything about 'pandas' but I intuited that
it could do what I want. I get, through the "read_excel" method, a
table similar to this:

  obj| foo1 foo2 foo3 foo4 foo5 foo6
  ---
 foo1|   aa   ab   zz   ad   ae   af
 |
 foo2|   ba   bb   bc   bd   zz   bf
 |
 foo3|   ca   zz   cc   cd   ce   zz
 |
 foo4|   da   db   dc   dd   de   df
 |
 foo5|   ea   eb   ec   zz   ee   ef
 |
 foo6|   fa   fb   fc   fd   fe   ff


And I would like to get a result similar to this:

{
'zz':[('foo1','foo3'),
  ('foo2','foo5'),
  ('foo3','foo2'),
  ('foo3','foo6'),
  ('foo5','foo4')
 ]
}

Would you show me the path, please?
Thank you in advance.

Yes, Jython 2 is currently more or less even with Python 2.7.

Help Needed With a Python Gaming Module

[WordWeaver Evangelist via Python-list]

Hello everyone! It has been a l-o-n-g time -- nine years in fact --since I last 
participated on this mailing list.

At that time, I was trying to write a door/external for my PC-ANSI, 
Macintosh-based BBS. Thanks to some of the folks here, I got it done  
although I eventually lost the module a number of years later when I left 
BBSing behind, because I assumed it to be dead.

Anyway, just recently I put my BBS back online again for the fourth time since 
1993, and I am again endeavoring to write a new python-based external -- a game 
-- for my BBS.

Before I continue, let me inform you that I am 70 years old, I am NOT a 
programmer, and I do not know any programming languages. Yes, I am a newbie, a 
noob, a greenhorn. :) So, if anyone here is willing to help me, you are going 
to need a lot of patience . like ChatGPT :)

Following the coding example of another open-source external that was written 
for my BBS, I have made some significant progress, thanks in large part to 
spending hours and hours chatting with ChatGPT over the past two days.

However, due my lack of expertise, and even though ChatGPT had me try all sorts 
of functions and codes and methods, there is one very perplexing issue which 
has prevented me from further development on my game. Even ChatGPT couldn't 
figure it out.

But before I get into the meat of the matter and waste everyone's time here, I 
need to address several questions to all of you Python brainiacs. )

Is there anyone -- or any group of someones -- amongst this noble assemblage, 
who meets all of the following qualifications:

1. You are very familiar with Mac OS 9.2.2

2. You are either moderately or very familiar with Hermes II BBS software.

3. You are very familiar with the Jython 2 environment, which I am told is 
based on Python 2 and NOT Python 3.

If you meet all three of those qualifications, then you may possibly be able to 
help me to overcome the mysterious obstacle I am now facing. Once I see what 
kind of responses I get, I will be very happy to share my nagging problem with 
you.

Thank you for taking the time to read this. Here is to hoping that my coding 
genius is out there, ready and eager to come to my aid.

Thank you in advance.

Kind regads,

Bill Kochman

RE: Can you help me with this memoization simple example?

[AVI GROSS via Python-list]

I am not sure if it was made clear that there is a general rule in python for 
what is HASHABLE and lists are changeable while tuples are not so the latter 
can be hashed as a simple copy of a list, albeit the contents must also be 
immutable.

The memorize function uses a dictionary to store things and thus the things are 
hashed to decide how to store it in the inner representation of a dictionary 
and anything new that you want to look up in the dictionary has similar 
considerations as it is hashed to see where in the dictionary to look for it.

Of course, if you add enough overhead and the memorize function you make gets 
relatively few requests that are identical, it may not be worthwhile.

'list' will iterate over args[0] to make a list, and 'sum' will
iterate
over that list.

It would be simpler to just let 'sum' iterate over args[0].

You can't use a list as a key, but you can use a tuple as a key,
provided that the elements of the tuple are also immutable.

You can't use a list as a key, but you can use a tuple as a key,

Yea, this problem comes up constantly (and has for many years).

People have suggested renaming the installer so it has "setup" or
"install" in the name.

People have suggested adding text to the installer splash screen to
explain that it's the installer and not python itself, that you
already have python installed, and if you want to _run_ python instead
of _install_ python, here's how.

People have suggested having the installer remove itself by default
when it's done installing.

People have suggested lots of solutions.

AFAICT, nobody has actually done anything.

I imagine the issue is trying get Python to run (as I recall, the python icon

I imagine the issue is trying get Python to run (as I recall, the python 
icon on the MS-Windows desktop is the installer, not Python itself).


that's often it, yes - you keep getting the installer when you think you 
should get a snazzy Python window. Of course, you don't - Python is a 
command-line/terminal program, not a windows app.  Now if you tried to 
launch IDLE instead, you'd get at least a window.


But we're just guessing here. Perhaps Chano will come back with an 
updated question with some details.

If you are just starting out, the most recent version is 3.12 and is
probably your best choice.

When you say it never worked, can you describe in more detail what you did

Mtg ANN: Using computer vision AI to help protect the worlds rarest dolphin

[dn via Python-list]

Wed 16 Aug 2023, 1800~20:30 NZST (0600~0830 UTC, late-Tue in US)
Details and RSVP at https://www.meetup.com/nzpug-auckland/events/295091858/


Teaching a computer to see. How computer vision is helping to protect 
the world’s rarest dolphin and how you can train your own model.


Tane van der Boon will talk about the MAUI63 project, and then lead us 
through how to train and utilise a custom computer vision object 
detector. Essentially allowing our software to be able to see.


MAUI63 was given its name because when the venture began, there were 
only 63 Māui dolphins left in existence. Using drone technology and AI 
to collect and process visual data, the founders took action to collect 
data to help save the world’s rarest dolphin from extinction and 
influence future marine conservation efforts.


The MAUI63 team uses a customised drone to find and track the movement 
of dolphins, and enables individual dolphins to be identified through 
their fin markings. The information collected can then be used to inform 
better data driven decisions on how best to protect them.


Later, Tane will lead us through a smaller task to build our own image 
recognizer. (more details in due course...)



The Auckland Branch of the New Zealand Python Users' Group meet twice 
monthly. You're very welcome to attend online or in-person (as 
available). Meeting location-details or URL will be sent to those who RSVP.


We are a healthy mix of Python users. Students, academics, hobbyists, 
industry professionals, and many completely new to Python.


The "room" opens at 1800 (local time) with an opportunity to network 
with colleagues. Everything should be wrapped up by 2030.


We are always keen to hear suggestions for meeting-topics, and to meet 
with folk who'd like to present or lead - eg a brief lightning talk, a 
practical coaching-session, a full lecture... Help is available if 
you've never done such a thing before!


We follow the NZPUG Code of Conduct (https://python.nz/code-of-conduct)

The argument type is ctypes.POINTER(ctypes.c_char_p), but that's not
sufficient. It doesn't implement converting a list of str objects into
an array of c_char_p pointers that reference byte strings. You could
write a wrapper function that implements the conversion before calling
func(), or you could set the argument type to a custom subclass of
ctypes.POINTER(ctypes.c_char_p) that implements the conversion via the
from_param() class method.

https://docs.python.org/3/library/ctypes.html#ctypes._CData.from_param

Here's an example of the latter.

C library:

#include 

int
func(void *obj, int index, char **opt)
{
int length;
for (length=0; opt[length]; length++);
if (index < 0 || index >= length) {
return -1;
}
return printf("%s\n", opt[index]);
}


Python:

import os
import ctypes

lib = ctypes.CDLL('./lib.so')
BaseOptions = ctypes.POINTER(ctypes.c_char_p)

class Options(BaseOptions):
@classmethod
def from_param(cls, param):
if isinstance(param, list):
new_param = (ctypes.c_char_p * (len(param) + 1))()
for i, p in enumerate(param):
new_param[i] = os.fsencode(p)
param = new_param
return BaseOptions.from_param(param)

lib.func.argtypes = (ctypes.c_void_p, ctypes.c_int, Options)


demo:

>>> opts = ['Opt1=DG', 'Opt1=DG2']
>>> lib.func(None, 0, opts)
Opt1=DG
8
>>> lib.func(None, 1, opts)
Opt1=DG2

Re: Help on ctypes.POINTER for Python array

[Jim Schwartz]

I’m not sure this is the shortest method, but you could set up two python 
scripts to do the same thing and convert them to c using cython. I wouldn’t be 
able to read the c scripts, but maybe you could. 

Maybe someone else has a more direct answer.

Help on ctypes.POINTER for Python array

[Jason Qian via Python-list]

Hi,

Need some help,

in the Python, I have a array of string

 var_array=["Opt1=DG","Opt1=DG2"]

I need to call c library and  pass var_array as parameter

In the   argtypes,  how do I set up ctypes.POINTER(???)  for var_array?

func.argtypes=[ctypes.c_void_p,ctypes.c_int, ctypes.POINTER()]

In the c code:

int  func (void* obj, int index,  char** opt)

Thanks
Jason

HOW do I get 3.11.3 on my desktop?


If you mean "How can I create a shortcut to Python 3.11.3 on my desktop 
that opens an interactive Python session", here is one way:


1. Find where your Python 3.11.3 program has been installed.  On the 
command line in a console, type:


py -c "import sys; print(sys.executable)"

You will get a response like this:

C:\Users\tom\AppData\Local\Programs\Python\Python311\python.exe

NOTE:  If the "py" command is not on your computer or does not open 
Python 3.11, then open a python 3.11 session and type the same commands:


import sys
print(sys.executable)

2. Open the Windows file browser ("Windows Explorer") and navigate to 
that directory.  On my computer this is


C:\Users\tom\AppData\Local\Programs\Python\Python311

3. Press and hold both the CTRL and SHIFT keys down at the same time, 
and with the mouse drag the icon for "python.exe" to a blank space on 
the desktop.  This will not drag the program itself but will create a 
shortcut and drag that.


4. Test the new shortcut by double-clicking on it and seeing that a new 
console window opens with the Python interpreter running in it.


If you do not like the size, shape, or font of this new console, change 
them by clicking on the icon in the upper left, then selecting 
"Properties", and making changes in the dialog box that opens.  The new 
choices will be used whenever you use this shortcut again.


5. The new shortcut will probably be named "python.ex".  I suggest that 
you rename it to "Python 3.11".  This way you can create other python 
shortcuts without having their names conflict.

I think you had better start using another name for this thread, if it
continues.

The HTML export file will contain the icons, but the HTML elements do
not provide for showing them.

I can't imagine how you can find anything among nor navigate through
1000 open tabs, let alone 10,000 in the future. I would think the memory
usage would be impossibly high. So I hope you are mostly using the
history and do not really have that many tabs open at once!



I am a plain guy, so if Firefox counted 1,000+ opened Tabs, I can be surprised, 
but have no idea how to check that number.

You are exactly right, icon URI and icon data come with saved opened Tabs,
a single example below.

So I am going to ask Firefox team to offer
export to html, modified to have :
icon, name of web page, url address
to appear in a single row (feature already supported by Firefox, when you open 
new Tab
and click: enter URL or search string - input field,
you get such list
List is limited in size for the reasons unknown to me, but feature works fine.


You should be aware that the HTML format for bookmarks is a standard 
developed back in the day by Netscape. It goes back to the early 1990s, 
I think. The FF folks will not be modifying it, since all browsers know 
how to generate it and consume it, and who knows how many software 
packages consume it.  No one can afford to have a change, even one 
that's supposed to be harmless, inadvertently break software that's 
worked for years.


They are going to need a lot of persuading.

Maybe there's something else they would be willing and able to do.  But 
you can expect that any proposed new feature will probably need to have 
some strong support.  Raymond Chen at Microsoft has written how each new 
feature proposal starts off with -100 points.  Only if the advantages 
get the score up above zero can the feature have any chance of getting 
adopted - and then it has to compete with other potential features that 
have their own scores.

Ok, I can export bookmarks to html file and open it in Firefox to get
a long list of clickable urls but icon of the bookmarked web page is missing.

When I open Bookmarks as right a side-bar I can view and identify an individual 
Boomarks by icon,
so I would like Firefox Library to export Bookmarks to html file, icons 
included ;)

Since accessing opened Tabs is my default use of history in Firefox and has

Ok, I was not aware of the real number of the opened Tabs in Firefox, since I 
can jump from left to right and vice versa in real time, so the number given by 
me: 50 opened Tabs was my general estimate, but I can read the real number of 
opened Tabs from the same menu (line below) to be 1,000+

What I copy and paste into Notepad++ is 1,000+ -line file.
It's hard to verify if the above number is made of opened Tabs only or 
bookmarks are included, 
since I exactly use and keep multi Tabs opened as my live bookmarks and cache 
memory, when I work on my projects (watching, counting sunspots,   Earthquakes 
prediction in Turkey, ... )

I would like to fund the development of such smart Tabs Manager to replace 
boomarks, to let me group Tabs belonging to different projects.

It doesn't look to be complicated, if supported by the Firefox team.

Firefox 97. comes with alike functionality (when I open a new Tab)  but limited 
to 4 rows of web-page icons + names and 4 rows called: Recent activity

All I need is to replace opened Tabs by history of the Recent activity - 
default Firefox page, when I open a new Tab

It's hard to imagine, I can have 1,000+ Tabs live opened in Firefox
but I really need such feature, called in the past as: MyLifeBits by MS

So I have to ask Firefox team today  to lift 4 rows limit on web links and 4 
rows limit on the recent activity, coming with
New Tab opened


When I am busy on a project I can open 100+ web pages via search engine  in one 
day and would prefer
100+ opened Tabs to be saved in html format for the records as a reference.

Hope to get some support from Firefox team via Twitter.

Ok, smart bookmarks manager can offer the above functionality right now, so I 
go to search engine to get one.

You can get that directly in Notepad++.  Load Firefox's HTML format 
bookmark file into Notepad++. View it in a browser using the "View/View 
Current File In" menu item. True, you could have opened it directly in 
the browser, but now you can edit the file and cut out the parts you 
don't need, and check to make sure you get what you intended. The 
structure of the HTML is very regular.


If you have saved your set of opened links under a distinctive heading 
near the top of the collection - as I suggested earlier - it should be 
easy to find the start and end points of their HTML elements, and delete 
all the ones you don't want. You could import this shortened bookmark 
file into another installation of Firefox and this would add them to the 
bookmarks in the other browser, all grouped by your custom heading.

I don't understand this. You don't really have 1000 tabs open at the 
same time, do you?  If you select all the open tabs - I think you wrote 
that you only have 50 - then you can save them as bookmarks under a 
folder name you choose. That folder will contain the 50 open links. I 
tried it this evening, so I know that's how it works. (It happens that 
I'm working on my own bookmark manager just now, so I've been messing 
around with importing, exporting, and reading the bookmark files).


Then you can export them and import the same bookmark file into another 
browser on another computer.  Whenever you want to reopen some of those 
tabs, you would navigate to that part of the bookmarks and open the tabs 
you want.


Maybe you have something else in mind?  Do you want to send the links of 
the opened tab set to someone else, but not all your bookmarks? Please 
explain more carefully what you want to do.

I can select All Opened Tabs (as from the given link)
and get 1,000+ Opened Tabs ( I am afraid, this is s number of all saved 
bookmarks in the past)
I go to menu, Bookmarks, Manage Boomarks and copy Tabs

and 
https://www.textfixer.com/html/convert-url-to-html-link.php

does the job, converting text urls into clickable web links

I copy the result and past into Notepad++ to save file as html

and what I get is web page of clickable Opened Tabs

since icon and page name are lost 
I would prefer another solution already ofered by Firex to generate web page of 
recently visited web pages,
unfortunately coming with  limits on the number of visited
web pages,
so I contacted Firefox, Notepad++ for help

This sounds like you mean when you get a new Windows 10 PC, you will
want to move your open tabs to the new machine. I see several
possibilities for this.

1. Copy your Firefox profile folder to the new computer, and tell
Firefox to use it as the default profile. I *think* this will include
the open tabs, but I haven't tried it. Saving that folder is useful for
backup anyway. (If you use Thunderbird for email, you really *must*
back up its profile folder because all your email with its folder
structure is there. BTW, you can even copy the profile over to a Linux
machine that has Thunderbird, and presto, all your email will be there.
The Firefox profile would probably transfer just as well).

2. Bookmark all your open tabs under a new heading "open tabs", then
export the bookmarks. In the new machine, import them into Firefox
there. They won't open in tabs, but it will be easy to find them and
open them when you want to. You probably will want to copy over your
bookmarks anyway, so this adds little effort.

3. There may be a specific record of open tabs that you can copy or
export. I don't know about this but an internet search should help.

Good luck.

Don't go pasting urls into a text file one by one.  Instead, do my #2

For that matter, the exported bookmarks file is an HTML file and can be

All right, I think I've got the easiest way to go.  You *can* bookmark 
all the tabs at once - see below.  Then, as I already proposed, export 
the bookmarks and import them into Firefox on the new computer.


To save the tabs, right click any one of them and select the "Select All

select the "Bookmark Tabs" item. A dialog box will open with an entry

Thank you Thomas for your excellent work you did for me.

Ok, I know, I need to switch to Windows 10 run on another PC next to me.

I need to learn how to copy and move every web page opened in Firefox as a 
reference to social media, web sites for Python, chat and more (about 50 web

I really love the limited functionality of w3schools to let me live open and 
run Python examples, especiallly Matplotlib examples.

Unfortunately chat forum at w3schools is low traffic, showing no interest to 
add more examples.

That's too bad; you may be out of luck.  It's possible that someone
has compiled the .pyd library in such a way that it does not need the
 instruction set extensions.  I'm sorry but I don't know how to find
out except by trying internet searches - or by downgrading to earlier
 versions of Numpy hoping to find one that works and also can be used
by the other libraries/programs that need to use it.


Here's a possibility to try -

https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

"NumPy: a fundamental package needed for scientific computing with Python.

Numpy+MKL is linked to the Intel® Math Kernel Library and includes
required DLLs in the numpy.DLLs directory.

Numpy+Vanilla is a minimal distribution, which does not include any
optimized BLAS libray or C runtime DLLs."

I didn't realize that Christoph Gohlke is still maintaining this site. I 
haven't needed to use it since PyPi got so much more complete about 
packages with binary code. He has tons of binary packages for all kinds 
of Python libraries.  I think this one might work for you because it 
links to the Intel math library. So it may be able to use various or no 
instruction set extensions. If so, it could work with your old processor.


Worth trying, anyway.

This exception has been reported to have many causes, but one
possibility seems to be that your computer may not support an advanced
instruction set that the .pyd was compiled for. I found this one
specifically mentioned on the Internet: Advanced Vector Extensions. If
that were the case, you would either need to find a different version of
the module, or upgrade the computer/OS.

It would be worth trying to downgrade the multiarray version to an
earlier one and see if that fixes the problem.

Thank you Thomas
for your kind reply.

I am fully aware to be living on an old machine, old OS, Windows 7, 32-bit 
system
but I have visited every social chat support forum on the Internet: from Python 
to Matplotlib, Numpy, Twitter, Github.

As a newbie I am not aware how to downgrade "the multiarray version to an
earlier one

I simply tried to test Python code from


https://www.section.io/engineering-education/reading-and-processing-android-sensor-data-using-python-with-csv-read/


# Python program to read .csv file

import numpy as np
import matplotlib.pyplot as plt
import csv


"After importing the libraries, we now read the .csv file:

with open('accl1.csv', 'r') as f:
data = list(csv.reader(f, delimiter=',')) #reading csv file


Just read about AVE from Wikipedia

https://en.wikipedia.org/wiki/Advanced_Vector_Extensions



downloaded and run
HWiNFO

Thank you Thomas for youre kind help.

You are the real Python PRO, you deserve Nobel Prize in Python.

:)


I operated an old Dell computer with Windows XP preinstalled
and upgraded XP to Windows 7 to get some web services to work.

Unfortunately I failed to find and install driver for video controller since 
none supported by Dell.

Visited many driver sites (Intel Driver Assistant included and more)
without any success.

So life with an old PC is not easy


I reused my 10-year-old Sony VAIO laptop (it had Windows 8, IIRC) to be 
a Linux machine - I got a 1T external solid state drive, set up the BIOS 
to boot from it, and installed Linux Mint.  If you are willing to tackle 
Linux, this might be a good way to go.  I recommend Mint for newcomers 
to Linux.  The computer is much snappier and pleasant to use than it was 
under Windows.


I mostly use it as a backup computer.  I had to to without my main 
computer for a week or so, and the old machine made a fine substitute. 
I even copied all my Thunderbird emails over and used email all the week 
without losing any messages. Actually, the keyboard on that old computer 
is much better than I've got on my new one, although a few keys are 
getting a little flaky.


I was able to compile some version of Python on it, though I forget why 
I needed to do that.  With this setup, you could install a newer version 
of Python, and Numpy would work - it might get compiled during 
installation, but that's not a problem.  It happens automatically.


If fact, I know that it works because I have Numpy working on the 
computer.  Of course, my computer has the instruction set extensions and 
your does not, so who knows if can be compiled for you.  But it would 
probably be your best bet.


Anyway, if you decide to try it out, let us know.  And if you hit any 
problems, I might be able to help you.  I'm not a Linux expert but I've 
installed various distributions maybe 20 times or more as virtual 
machines, and twice using an external drive, including running Tomcat 
and MySQL as services.  Once you get it installed and working, and 
learned some of its quirks (not too bad, mostly about installing 
programs and configuring the desktop to be more to your liking), it's 
not much diff

Thank you Thomas for youre kind help.

You are the real Python PRO, you deserve Nobel Prize in Python.

I operated an old Dell computer with Windows XP preinstalled
and upgraded XP to Windows 7 to get some web services to work.

Unfortunately I failed to find and install driver for video controller since 
none supported by Dell.

Visited many driver sites (Intel Driver Assistant included and more)
without any success.

So life with an old PC is not easy

This exception has been reported to have many causes, but one
possibility seems to be that your computer may not support an advanced
instruction set that the .pyd was compiled for. I found this one
specifically mentioned on the Internet: Advanced Vector Extensions. If
that were the case, you would either need to find a different version of
the module, or upgrade the computer/OS.

It would be worth trying to downgrade the multiarray version to an
earlier one and see if that fixes the problem.

That's too bad; you may be out of luck.  It's possible that someone has 
compiled the .pyd library in such a way that it does not need the 
instruction set extensions.  I'm sorry but I don't know how to find out 
except by trying internet searches - or by downgrading to earlier 
versions of Numpy hoping to find one that works and also can be used by 
the other libraries/programs that need to use it.

Thank you Thomas for your kind reply.

I am fully aware to be living on an old machine, old OS, Windows 7,
32-bit system but I have visited every social chat support forum on
the Internet: from Python to Matplotlib, Numpy, Twitter, Github.

I mentioned the "multiarray" just because of its name in the error message:

"Error module name: _multiarray_umath.cp38-win32.pyd "

I assumed that the code you tried to run required an import from a
module or package whose name included "multiarray".  But I didn't try to
actually look for one.  Now I've checked, and I see it's included with
NumPy.


I simply tried to test Python code from


https://www.section.io/engineering-education/reading-and-processing-android-sensor-data-using-python-with-csv-read/

  # Python program to read .csv file

import numpy as np import matplotlib.pyplot as plt import csv 

"After importing the libraries, we now read the .csv file:

with open('accl1.csv', 'r') as f: data = list(csv.reader(f,
delimiter=',')) #reading csv file


You don't need numpy just to do this import, so you could remove the
numpy import just to test reading the csv file.  But I imagine you do
need numpy for later steps.



As a newbie I am not aware how to downgrade "the multiarray version
to an earlier one.
I just had to do this myself to work around a change in an import that 
broke one of my programs (not a numpy import).  If you can identify an 
earlier version that work - we will use proglib v 3.72 as an example - 
with pip you would use


python3 -m pip install --upgrade proglib<=3.72

To get exactly version 3.72, you would use "==3.72".

NOTE - no space allowed before the first "=" character!.
NOTE - you may need to type "python" or "py" instead of "python3".  Just 
use the one that runs the version of Python that you want to run.


To find which versions are available:

python3 -m pip install --upgrade proglib==

To find out which version you have installed on your computer:

python3 -m pip show numpy

After you downgrade to an earlier version, you can test it just by 
trying to import numpy.  In an interpreter session, just try to import it:


>>> import numpy

If that succeeds, chances are you will be all set.


 Just read about AVE from Wikipedia

https://en.wikipedia.org/wiki/Advanced_Vector_Extensions


I have read that there are other instruction set extensions that could 
be missing besides AVE, that could cause that exception code.  The fact 
that you have a relatively old computer suggests that could be the problem.

It works, but when I run it with the -h option it dumps all entries in

and I ended up with

class CustomHelpFormatter(argparse.HelpFormatter):

This works, but is there a more elegant way to achieve it?


It may be sufficient to specify a metavar:

>>> import argparse
>>> p = argparse.ArgumentParser()
>>> p.add_argument("--foo", choices="alpha beta gamma".split(),
metavar="")
[...]
>>> p.parse_args(["-h"])
usage: [-h] [--foo ]

optional arguments:
  -h, --helpshow this help message and exit
  --foo 

While that helps with --help it doesn't always prevent the choices list
from being spelt out:

>>> p.parse_args(["--foo", "whatever"])
usage: [-h] [--foo ]
: error: argument --foo: invalid choice: 'whatever' (choose from
'alpha', 'beta', 'gamma')

What happens if you just presupply a `help=` parameter in

-h still shows all the contents of pytz.all_timezones.



Adding a few arguments makes it work (with the help of the argparse doc 
page and Stack Overflow:


https://stackoverflow.com/questions/14950964/overriding-default-argparse-h-behaviour):

import argparse
import pytz

HELP ="""\nThis is the help message.

def main():
parser = argparse.ArgumentParser(add_help=False, usage = HELP)
parser.add_argument("-z", "--zone", choices=pytz.all_timezones,

parser.add_argument('-h', '--h', action = 'help',
help = argparse.SUPPRESS)
args = parser.parse_args()
print(args)
print(f"Specified timezone: {args.zone}")


main()

Your help message will display after "usage", like this -

usage:
This is the help message.
This is the second line of the help message.

You would give up have argparse automatically list all the options, but 
you can add add them manually to the HELP string.

Re: Custom help format for a choice argparse argument

[Weatherby,Gerard]

Why not something like:

parser.add_argument("-z", "--zone")
   args = parser.parse_args()
   if args.zone and args.zone not in ptyz.all_timezones:
print(“Invalid timezone”,file=sys.stderr)

*** Attention: This is an external email. Use caution responding, opening

Hello,

I am developing a script that accepts a time zone as an option. The
time zone can be any from pytz.all_timezones. I have

def main():
parser = argparse.ArgumentParser()
parser.add_argument("-z", "--zone", choices=pytz.all_timezones)
args = parser.parse_args()
print(args)
print(f"Specified timezone: {args.zone}")

It works, but when I run it with the -h option it dumps all entries in
pytz.all_timezones. I would like to modify the help format for just
-z|--zone option. I read the docs about HelpFormatter and argparse.py
and I ended up with

class CustomHelpFormatter(argparse.HelpFormatter):
def _metavar_formatter(self, action, default_metavar):
if action.dest == 'zone':
result = 'zone from pytz.all_timezones'

else:
return (result, ) * tuple_size
return format
else:
return super(CustomHelpFormatter,

parser.add_argument("-z", "--zone", choices=pytz.all_timezones)

The need to set `LD_LIBRARY_PATH` usually can be avoided via
a link time option: it tells the linker to add library path
information into the created shared object.

Read the docs to find out which option this is (I think it
was `-r` but I am not sure).

It might be necessary, to provide the option mentioned above
for all shared libraries involved in your final application.

Alternatively, you could try to put the shared objects
into a stadard place (searched by default).

Again: either put your installation in a standard place
or tell the Python generation process about your non-standard place.

[Help Request] Embedding Python in a CPP Application Responsibly & Functionally

[John McCardle]

Greetings,

I'm working on embedding a Python interpreter into a C++ application. My 
embedding example program is here, largely taken from Python docs: 
https://gist.github.com/jmccardle/f3f19d3753ae023aa52b927f0d181c43


I'm simply not interested in writing in Lua, so regardless of any 
particular downsides like `sys` in the standard library or performance 
issues, I'm committed to Python itself as what I want to hack in. This 
is for fun.


I started by compiling Python:

`./configure --enable-shared --enable-optimizations`

Then I can compile my example embedded program:

`g++ -I Python-3.11.1/Include -I Python-3.11.1 -L Python-3.11.1 -pthread 
scripting_engine.cpp libpython3.11.a -o scripteng -lm -ldl -lutil`


This is working not so bad! I can control what C++ functionality is 
exposed and I seemingly don't need anything but the Python shared object 
to execute. But the finer details of making this work truly correctly 
are eluding me.


1) To get the compiled Python to run independently, I have to hack 
LD_LIBRARY_PATH to get it to execute. `LD_LIBRARY_PATH=./Python-3.11.1 
./Python-3.11.1/python` . Even when trying to execute from the same 
directory as the binary & executable, I get an error, `/python: error 
while loading shared libraries: libpython3.11.so.1.0: cannot open shared 
object file: No such file or directory`.


2) When running the C++ program that embeds Python, I see these messages 
after initializing:

`Could not find platform independent libraries 
Could not find platform dependent libraries `

This is seemingly connected to some issues regarding libraries: When I 
run the Python interpreter directly, I can get some of the way through 
the process of creating a virtual environment, but it doesn't seem to 
leave me with a working pip:


`$ LD_LIBRARY_PATH=./Python-3.11.1 ./Python-3.11.1/python
>>> import venv
>>> venv.create("./venv", with_pip=True)
subprocess.CalledProcessError: Command 
'['/home/john/Development/7DRL/cpp_embedded_python/venv/bin/python', 
'-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit 
status 127.`


Meanwhile, if I try to run a script from the C++ program that includes 
`import venv`, I get a traceback about a platform library:


`Traceback (most recent call last):
  File "engine_user.py", line 7, in 
    import venv
  File 
"/home/john/Development/7DRL/cpp_embedded_python/Python-3.11.1/Lib/venv/__init__.py", 
line 10, in 

    import subprocess
  File 
"/home/john/Development/7DRL/cpp_embedded_python/Python-3.11.1/Lib/subprocess.py", 
line 104, in 

    from _posixsubprocess import fork_exec as _fork_exec
ModuleNotFoundError: No module named '_posixsubprocess'
`

3) I'm not sure I even need to be statically linking the interpreter.

My desired end state is this:
* Deploy a C++ program that doesn't rely on a system Python. I'm not 
sure if I need just the shared object / DLLs, or a Python executable in 
a subdirectory - I'd like to "do it the right way".
* C++ program can run a script to create a virtual environment, which 
the embedded Python environment will use. Users can activate the venv 
like any other Python environment and install packages with pip.
* ideally, some sort of "inside-out" runnable mode, where the API 
exposed by the C++ executable is available in that venv, so that I can 
test a script in Thonny or other IDE. I think I'd do this by providing a 
separate test-mode library in the venv, and when C++ executes 
`PyImport_AppendInittab("scriptable", _scriptable);` then the 
module of the same name should be overwritten with the C++ program's 
functionality.


I've been through the embedded programming docs a bit, and they seem 
quite good as a reference, but I don't know what I'm doing well enough 
to solve my problems using them. Thanks for reading.


My ultimate goal is to expose features written in C++ for a game engine 
using SFML, and run .py files in a subdirectory to generate maps, 
control NPC dialogue and actions, etc. I'm hoping to have something 
usable for this year's 7DRL, which starts March 4th. I'd like to spend 
the time until then getting this engine working smoothly and porting it 
to Windows, so I can focus exclusively on "game content" for the 
timeboxed 7-day portion.


Kind Regards,
-John McCardle

Nice, I didn't know that one could multiply strings by negative numbers without

   Thanks, but today I thought that maybe there might
   be a solution for getting a field of a fixed length
   that is even shorter. It uses Python's string
   formatting, here in the form of an "f" string.

   main.py

def f( result, length ):
 # get a field with the given length from the string "result"
 # - as used in postings from october
 result = result[ :length ]
 result += ' ' *( length - len( result ))


That can be done more compactly as:

 result = result[ : length].ljust(length)


 return result

Port 587 is not the standard TLS port. Port 587 is the standard mail
submission port (i.e., a MUA should use port 587 when sending mail; MTAs
should use port 25 when relaying mails to other MTAs).

Traffic on both port 25 and 587 starts in plain text. The server can
indicate that it supports TLS and the client can then send a STARTTLS
command to start a TLS session.

If you want to start the connection with TLS, you can (usually) use port
465. Like 587, this is only intended for mail submission, not mail
transport.

2525 is an alternative to 587, the standard TLS port.


Yah. My point was more focussed on GMail's shoddy firewall practices not 
returning connection refused.



25  and 587 work.

2525 is an alternative to 587, the standard TLS port. 25  and 587 work.

This usually means that either the host address is legal but incorrect 
(there's no host/server listening with that address) or that the port is 
incorrect and some firewall is _discarding_ your traffic because of the 
wrong port instead of returning a nice "connection refused", which is 
usually instant.


Fortunately you've listed your call:

    File "C:\Users\i9shu\Downloads\python email bot\email bot.py", 
  line 25,

  in 
      server = smtplib.SMTP('smtp.gmail.com',2525)


So, I'll try that by hand here:

% telnet smtp.gmail.com 2525
Trying 142.250.4.108...
telnet: connect to address 142.250.4.108: Operation timed out

telnet: connect to address 2404:6800:4003:c0f::6d: No route to host

I'd say GMail are rudely dropping traffic to port 2525. Maybe try just 
25, the normal SMTP port?

Why do you prefer super().format_field() over plain format()? The doc says:
"format_field() simply calls format()." So I figured I might do the same.


 I am not aware of any reason not to call "format" directly.


Stefan's code implements it's own format_field and falls back to the 
original format_field(). That's standard subclassing practice, and worth 
doing reflexively more of the time - it avoids _knowing_ that 
format_field() just calls format().


So I'd take Stefan's statement above to imply that calling format() 
directly should work.


My own habit would be to stick with the original, if only for semantic 
reasons. Supposing you switched from subclassing Formatter to some other 
class which itself subclasses Formatter. (Yes, that is probably 
something you will never do.) Bypassing the call to 
super().format_field(...) prevents shoehorning some custom format_fields 
from the changed superclass. Which you'd then need to debug.


That's all.

Need help with custom string formatter

[Robert Latest via Python-list]

Hi all,

I would like to modify the standard str.format() in a way that when the
input field is of type str, there is some character replacement, and the
string gets padded or truncated to the given field width. Basically like
this:

fmt = MagicString('<{s:6}>')
print(fmt.format(s='Äußerst'))

Output:


I've written a function fix_format() which, given a string and a field width,
does just that. However, I find myself unable to implement a Formatter that
uses this function in the intened way. See the example below, I hope I
sprinkled it with enough comments to make my intents clear.  Thanks for any
enlightenment. The interesting part starts somewhere in the middle.

### Self contained example
import re
from string import Formatter

_replacements = [(re.compile(rx), repl) for rx, repl in (\
('Ä', 'Ae'),
('ä', 'ae'),
('Ö', 'Oe'),
('ö', 'oe'),
('Ü', 'Ue'),
('ü', 'ue'),
('ß', 'ss'))]

def fix_format(text, width):

# Seven regex passes seems awfully inefficient. I can't think of a
# better way. Besides the point though.
for rx, repl in _replacements:
text = re.sub(rx, repl, text)

# return truncated / padded version of string
return text[:width] + ' ' * max(0, width - len(text))

class Obj():
"""I'm just an object with some attributes"""
def __init__(self, **kw):
self.__dict__.update(kw)

o = Obj(x="I am X, and I'm too long",
y="ÄÖÜ Ich bin auch zu lang")
z = 'Pad me!'

format_spec = '<{o.x:6}>\n<{o.y:6}>\n<{z:10}>'

# Standard string formatting
print('Standard string formatting:')
print(format_spec.format(o=o, z=z))

# Demonstrate fix_format()
print('\nWanted output:')
print('<' + fix_format(o.x, 6) + '>')
print('<' + fix_format(o.y, 6) + '>')
print('<' + fix_format(z, 10) + '>')

# This is where my struggle begins. #

class MagicString(Formatter):
def __init__(self, format_spec):
self.spec = format_spec
super().__init__()

def format(self, **kw):
return(self.vformat(self.spec, [], kw))

def get_field(self, name, a, kw):
# Compound fields have a dot:
obj_name, _, key = name.partition('.')
obj = getattr(kw[obj_name], key) if key else kw[obj_name]
if isinstance(obj, str):
# Here I would like to call fix_format(), but I don't know where
# to get the field width.
print('get_field(): <' + obj + '>')
else:
# Here I'd like to use the "native" formatter of whatever type
# the field is.
pass
return obj, key

def get_value(self, key, a, kw):
'''I don't understand what this method is for, it never gets called'''
raise NotImplementedError

fmt = MagicString(format_spec)
print('\nReal output:')
print(fmt.format(o=o, z=z))

# Weirdly, somewhere on the way the standard formatting kicks in, too, as

Re: Need help with custom string formatter

[Robert Latest via Python-list]

Hi Stefan, 

I have now implemented a version of this, works nicely. I have a few minor
questions / remarks:

>   result += ' ' *( length - len( result ))

Nice, I didn't know that one could multiply strings by negative numbers without
error.

> def __init__( self ):
> super().__init__()

Isn't this a no-op? Probably a leftover from my stuff.

> def format_field( self, value, format_string ):
> if re.match( r'\d+', format_string )and type( value )== str:

Why do you prefer re.match(r'\d+', x) over x.isdigit()?

> return super().format_field( value, format_string )

Why do you prefer super().format_field() over plain format()? The doc says:
"format_field() simply calls format()." So I figured I might do the same.

Thanks!

Re: Fwd: Can you help me with this Python question?

[Axy via Python-list]

Well, although I never used pandas and never will, if that's about 
artworks, that's mine.


Obviously, you need to iterate columns and sum values returned by the 
snippet you provided. A quick search tells us to use colums property. 
So, it might look like this:


na_sum = sum(df[name].isnull().sum() for name in df.columns)

Indentation depends upon what went before, as well as what is being

Indeed... what you've posted, with the exception that we don't see what
these two _df values are:

t1 = Time_sensitive_df
...
t3 = normal_df

looks basically workable for what it is.

Guessing at your intent here - presumably you want your chain to be
persistent and not be created from scratch each time you go to access
it. You *could* use a database for this, and there are lots of Python
technologies for talking to databases, but there's none of that in your
code so we can't comment on it.

For early experiments you could just use a text file.  Then you need to
code a way to load the existing chain from the file into your working
copy, if the file exists, rather than instantiating a copy of
Blockchain, which will always start over:

def __init__( self ):
self.chain = [ ]
self.generate_genesis_block()

since the chain itself is a list, perhaps you could dump that list to a
json file, and reload it into self.chain if the json file is found to
exist, instead of doing the initial-setup?

Apologies if I have completely misunderstood what you are seeking...

As I understand the documentation, The last is Apple
specific/non-standard information...
https://eyed3.readthedocs.io/en/latest/eyed3.id3.html

"""
eyed3.id3.apple module

Here lies Apple frames, all of which are non-standard. All of these would
have been standard user text frames by anyone not being a bastard, on
purpose.
"""

{I'm not thrilled by the documentation -- it is basically a collection on
one-line doc-strings with absolutely no hints as to proper usage}

>  File "/Documents/Python/Test1/main.py", line 94, in 
>myCDID = myID3.id3.frames.MusicCDIdFrame(id=b'MCDI', toc=b'')
>AttributeError: 'Mp3AudioFile' object has no attribute 'id3'

"""
 eyed3.core.load(path, tag_version=None)[source]

Loads the file identified by path and returns a concrete type of
eyed3.core.AudioFile. If path is not a file an IOError is raised. None is
returned when the file type (i.e. mime-type) is not recognized. The
following AudioFile types are supported:

eyed3.mp3.Mp3AudioFile - For mp3 audio files.

eyed3.id3.TagFile - For raw ID3 data files.
"""

eyed3.id3. would appear to be specific to non-MP3 data files.

So... I'd try the interactive environment and check each layer...

dir(myID3)

(based upon the error, there will not be a "id3" key; so try
dir(myID3.) for each key you do find).

Given this bit of source code from the documentation...

def initTag(self, version=id3.ID3_DEFAULT_VERSION):
"""Add a id3.Tag to the file (removing any existing tag if one
exists).
"""
self.tag = id3.Tag()
self.tag.version = version
self.tag.file_info = id3.FileInfo(self.path)
return self.tag

... you probably need to be looking at 
myID3.tag.

... try
dir(myID3.tag)
and see what all may appear...

IOW: the ID3 information has already been parsed into separate "tag"
fields.

Sounds like you're launching it already?

In a cmd shell, type:
