Re: The following modules appear to be missing ['_sysconfigdata']
OK, stop the presses. Or, rather, refresh your browser, I guess.
In a 'what the !@#$ am I doing'-moment (I don't get those often) I uninstalled
everything and went gardening. But it was raining so I installed everything
again, this time using pip for wxpython. Lo and behond, this time it did not
crash the cmd-window, but in stead it successfully installed it.
Woot.
Then I compiled again with same command and same setup-py and - stubbornly -
with py2exe, and got… different errors! That's actually I good sign. No, really.
Because this time, the error was about missing Windows DLLs and for these I got
plenty of help from my best friend Google (don't tell JackD he's actually
second best friend). So, after x iterations I ended up with the following cute
setup.py:

Re: The following modules appear to be missing ['_sysconfigdata']
Oh, another thing. I installed WX via a windows installer that I found (can't find the link again, but fairly certain it was this one: https://sourceforge.net/projects/wxpython/ (*)), without giving it much thought (yesyes bad mistake). Since I get wx runtime errors, I'm assuming I have the wrong version. So, in all my 45-yo youthful ignorance, I ran 'pip install -U wxPython' hoping it would magically erase the previously installed version - whatever that is - and get me the newest one. What actually happens is the cmd-window freezing, and nothing else… (*) The 'proper' method to install it, I obviously found on "https://wiki.wxpython.org/How%20to%20install%20wxPython#Windows;, but that led me to 'pip', which at that moment in time - 2 days ago LOL - I was not ready for yet (Hey, I'm doing this in between actual work, putting kids in bed, and passing out on the sofa) -- https://mail.python.org/mailman/listinfo/python-list
Re: The following modules appear to be missing ['_sysconfigdata']
Really, no-one? OK, more purging then. I ~think~ I need said missing component because the script gets the system date (to run once on a Friday, in automatic mode). But I've never used it in automatic mode (since I came to my senses about having an infinite looping script in my autoexec.bat, doing nothing, except executing once on a friday, and wasting resources). So, if I scrap the automatic mode, I guess I might finally have something that 'works'. Still disappointed though that I can't get it to work again with the same 'tools' as previously. Especially since I also use the date to add to the name of the backup files that the script is making. Oh, as for 'distributing' this thing. It's a private/personal script, so I'm my only customer. In this sense, I don't even need the EXE now that I've scrapped automatic mode. I can just run the *.py straight from a console. Oh well. Would anyone be interested in seeing the - now infamous - script, to have a go yourself? -- https://mail.python.org/mailman/listinfo/python-list
Re: The following modules appear to be missing ['_sysconfigdata']

I am a tad afraid you're giving me a bit too much credit though; it's all a bit Chinese to me. (I'm not Chinese, BTW, but I'm not making up these expressions myself so there's that). Step 2 you've lost me already. What is virtualenv, and why do I need it (this time round, not last time when I got it to work)? You don’t really need to respond, this is more of a rethorical question :). Step 3 is I think the real issue. At first I was missing 'wx' and '_sysconfigdata', so I installed wxPhyton (via a windows installer that I found, not with pip), and that made the compile error go away (though it still throws runtime errors, of course). But what is '_sysconfigdata', and how do I install it? I - and pip :) - can't find a repo with that name!? step 5, pyinstaller, is yet another hurdle I hope to avoid. It worked with py2exe, and it should still work with py2exe (within the efforts I'm prepared to put into this). Of
The following modules appear to be missing ['_sysconfigdata']
Hello, first time using python groups (and long time since using any other group for that matter). This might not be the right group due to wx being involved. Long story as short as possible. I have an old python script that I did ~10 years ago, and have forgotten basically everything about Python since then (sorry!). Converted it to EXE way back when, and have kept using the EXE ever since then (on XP, and on Win7). I've just gotten a new PC, Windows10 (!), needed to update the script, so needed to recompile the EXE, and now it no longer compiles/works. It was fine on Windows7 (I'm not specifically stating that the problem is with windows10 - I simply don't remember all the hoops I jumped through on my previous machine). Here is the compile error: The following modules appear to be missing ['_sysconfigdata'] And here is the runtime error: Traceback (most recent call last): File "AutoArchive.py", line 3, in File "wx\__init__.pyc", line 45, in File "wx\_core.pyc", line 4, in File "wx\_core_.pyc", line 12, in File "wx\_core_.pyc", line 10, in __load ImportError: DLL load failed: %1 is not a valid Win32 application. Here is how I compile: python setup.py py2exe And this is my setup.py: from distutils.core import setup import py2exe setup(console=['AutoArchive.py']) Yes, that says 'console' for a Windows EXE, but swapping it to 'window' didn't help. Besides which, the setup.py file is straight from the old computer, so 'it used to work'. What I have installed: . python 2.7.13 (this in itself may be a problem - I don't even remember which version I was using earlier, other than knowing for sure it wasn't a 3.x release) . wxpython (since I also got an error that wx module was missing - that rang some bells, since the script uses a Windows pop-up window to inform me about its progress, and I remember using wx for that, so I installed it, but don't know how to get its' version. using "python -c "import wx;print wx.__version__" just gives runtime errors). Any help would be appreciated. And yes, I googled, but can't really find anything (well, d'Uh!, I wouldn’t be here then would I?) - there's ~some~ references, but usually it's about similar issues on Linux, with solutions that are not applicable at all. Except one I thought: I found some link stating that _sysconfigdata is part of sysconfig, and that this needed to be installed with pip, so I used the pip that came with my python distro and did 'pip install [[_]sys]config[data]' (all possible combo's) but pip claims it can't find said module, and TBH, I can't seem to find anything myself about said module.

[issue33129] Add kwarg-only option to dataclass
Jimbo Jim added the comment: first post in bugs.python.org... are people normally scary around here? Another usecase of keyword-only arguments is that I can mix default and non-default fields in any order. This could be achieved by either marking all fields as read-only, or by implicitly adding an asterisk before the first "conflicting" non-default argument (or by translating .../etc into an asterisk). (Is it a bad idea to create a private fork of `pip install dataclasses` with implicit asterisk, purely for my own project?) -- nosy: +Jimbo Jim ___ Python tracker <https://bugs.python.org/issue33129> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[WxPython] Advice on Temperature Application Method Structure
Hello I have made a simple application using WxPython that is a temperature converter. This is my first application made in WxPython, the only other apps I have made were in Win32 c++ so I am new to widgets in general. I am looking for advice criticism on when you should use classes in GUI widget apps ( where) other general advice: - Structure of a wxPython script/code - Should every window be in its own class? - whats the best way to refer to a control (by window name or ID) - Should a group of controls that are related be in a class For example should I make a Celsius class that handles the celsius editbox, static button the button action function(convert_to_fahrenheit())? - Errors, bad things I have done in my code - When why use a Validator??

Extract all words that begin with x
Hello
I am trying to find if there is a string OR list function that will
search a list of strings for all the strings that start with 'a'
return a new list containing all the strings that started with 'a'.
I have had a search of Python site I could not find what I am
looking for, does a function like this exist?
The only one that I think could work is, use the string
function .count()
algorithm: to exract all the words inside a list that start with 'a'
- make sure the list is arranged in alphabetical order
- convert the list to a big string
- use list_string.count(',a') to obtain the index where the last 'a'
word occurs
- convert back into string (yes this is a REAL hack :P)
- and then create a new list, ie, new_list = list[0:32]
- return new_list
Ok that algorithm is terrible, I know, I just realise that it wont
work for letters after 'a'. So if anyone could suggest a function or
algorithm it would be extremely helpful

Simple Cookie Script: Not recognising Cookie
Hi I have a simple Python program that assigns a cookie to a web user
when they open the script the 1st time(in an internet browser). If
they open the script a second time the script should display the line
You have been here 2 times. , if they open the script agai it
should show on the webpage You have been here 3 times and so on.
But for some reason, my program is not assigning or recognising an
assigned cookie outputing the line You have been here x times. I
have gone over my code for like 2 hours now I cant figure out what is
going wrong??
Can you help me figure out whats wrong? I have my own cgi server that
just runs on my machine so its not that its the code to recognise/
assign a cookie
[code]#!/usr/bin/env python
import Cookie
import cgi
import os
HTML_template =
html
head
/head
body
p %s /p
/body
/html
def main():
# Web Client is new to the site so we need to assign a cookie to
them
cookie = Cookie.SimpleCookie()
cookie['SESSIONID'] = '1'
code = No cookie exists. Welcome, this is your first visit.
if 'HTTP_COOKIE' in os.environ:
cookie = Cookie.SimpleCookie(os.environ['HTTP_COOKIE'])
# If Web client has been here before
if cookie.has_key('SESSIONID'):
cookie['SESSIONID'].value = int(cookie['SESSIONID'].value)
+1
code = You have been here %s times. %
cookie['SESSIONID'].value
else:
cookie = Cookie.SimpleCookie()
cookie['SESSIONID'] = '1'
code = I Have a cookie, but SESSIONID does not exist
print Content-Type: text/html\n
print HTML_template % code
if __name__ == __main__:
main()

Advice Criticism on Python App
I have made a Python App(really script) that will check a stocks current values from a website save that data to a SQLite 3 database. I am looking for any suggestions criticisms on what I should do better or anything at all but mainly in these areas: [QUOTE] - Correct Python Layout of code - Correct error checking: Am I catching all my errors or are my exceptions not specific enough? Should I be using more try excepts inside my functions? - Are there any areas where huge errors, bugs etc could occur that I have not compensated for? - I am also looking for suggestions on how to write a function better, so if you think that function is really bad should be rewritten completely or something I would really like to hear it. - Anything else that you see - Is python meant to be used in the way I have used it? To make a 'semi detailed' app?[/QUOTE] Any advice criticism would be really helpful.

You should use BeautifulSoup or perhaps regular expressions.
Or if you are not very smart, lik me, just try a brute force approach:
for i in s.split(''):
for e in i.split():
if '.' in e and e[0].isdigit():
print (e)
43.200
0.040
43.150
43.200
43.130
43.290
43.100
- Hide quoted text -
- Show quoted text -- Hide quoted text -
- Show quoted text -
Thanks very much, I'm going to look at regular expressions but that
for your code, it shows me how I can do it iwth standard python :)

Python Script to get Info from Site not working
Hello I am asking what is probably a very easy thing to do but I cannot find a tutorial on how to do it anywhere. [b]I want to use a Python script to get information from a webpage. [/b] I found a semi Python internet tutorial here if anyone else would like it http://www.upriss.org.uk/python/session6.html I would like to create a python script that gets a value from a set of radio buttons on a HTML page tell me which one is selected. I have 3 radio buttons: Tea, Coffee, Hot Chocolate a Submit button My script is meant to find which radio button is selected tell me that. But it just keeps saying No Drink Selected! Can you help me figure out how to fix this. FYI: My Python script my HTML page are both saved in the same directory. And I made the webpage using Notepad++, I open the webpage in Interent Explorer I made the Python Script in Idle.

Replace the last line with something like this, to see what you are getting exactly: print(Sorry, no %r (%r) available. % ( drink, cgi.escape(repr(type(drink) BTW, which Python version are you using? The tutorial you linked to is aimed at Python 2.x, but your print syntax suggests you're using Python 3.x -- Gabriel Genellina Yeah that(You need to select a drink!) was the string I was getting but I should be getting hot chocolate or something else(which ever one I have selected) I am using 3.x, do you think I should be using something else?

bdb
Hi,
I am trying to sort how to best programmatically run the debugger on a
program, and another way that I am trying to explore is by using the
bdb module. There isn't any documentation for this and I have tried
reading through the source, which includes an example/test at the end
of bdb.py on Python 2.3/OS X.
What I can't figure out is how this might work if you wanted to have
the function 'step' through each line. I see various functions that
suggest that they might be for this but I can not get anything to work.
Has anyone any suggestions or point me in the direction of any other
docs?
Thank you!
jms.
From the bdb.py:
def test():
t = Tdb()
t.run('import bdb; bdb.foo(10)')
where Tbd subclasses Bdp and overrides the user_ methods (see around
line 533 of bdb.py. But what about set_step()? Or am I way off here?

debugging process
Hi, I am trying to create a separate process that will launch python and then can be used to step through a script programmatically. I have tried something like: (input, output) = os.popen2(cmd=python) Then I expected I could select over the two handles input and output, make sure they aren't going to block, and then be able to write python code to the interpreter and read it back. I intend to import a module, run it in the debugger with pdb.run() and the start passing debug commands in and read the output. I hope that makes sense, what I am finding is that whenever I try to read from the output handle it blocks. My understanding was that if it is returned by select that it is ready for reading and won't block. I think that this must have something to do with python expecting itself to by in a TTY? Can anyone give any idea of where I should be going with this? Thanks, jms. [EMAIL PROTECTED] http://www.cordiner.com -- http://mail.python.org/mailman/listinfo/python-list
