[issue44709] [3.7] Popen Control Characters in stdout affect shell session

[San]

San  added the comment:

I just realised that this is not a problem of python but rather a problem of 
the shell that I was using. I was testing the io in a different environment. 
Now I retried in the same environment that the wrapper was operating and the 
behaviour is the same using io.

Sorry for the confusion and thanks for nudging me the right direction.

[issue44709] [3.7] Popen Control Characters in stdout affect shell session

[San]

San  added the comment:

I get your point. But I thought setting 'stdout=PIPE' should not send the 
stdout directly to the terminal but rather through the pipe first?!

Also what you're saying seems to contradict that this doesn't happen if I don't 
set the encoding and let it be a byte-stream. In that case you get the full 
byte-stream without any control-characters being executed.

In my opinion it is unintuitive that this is happening. 

For instance if I open a file using io, that contains the same control 
characters like so:
f = open('cc.txt', 'r', encoding='latin_1')

Then gladly this doesn't happen and the control chars get escaped using \x1b 
which is what I would also expect to happen when using Popen.

[issue44709] [3.7] Popen Control Characters in stdout affect shell session

[San]

New submission from San :

I was trying to wrap an old game server executable with a built-in console 
using Popen.

class ServerWrapper(Thread):
def __init__(self, pathToExecutable: str, statusMonitor: Popen = None, 
active: bool = False):
super().__init__()
self.pathToExecutable = pathToExecutable
self.statusMonitor = statusMonitor
self.active = active

def run(self):
self.statusMonitor = Popen(['./bf1942_lnxded', "+statusMonitor", '1'], 
encoding='latin_1', stdout=PIPE,
   stdin=PIPE, cwd=self.pathToExecutable)
while self.active:
currentLine = self.statusMonitor.stdout.readline()
if currentLine:
print(currentLine)
input('')

def start(self):
self.active = True
super().start()

def stop(self):
self.active = False



I expected to be able to read the output line-by-line using enter, in a 'normal 
fashion'.
After importing this from a terminal and setting it up somewhat like so:

wrapper = ServerWrapper('bf1942')
wrapper.start()

However, once the server process started and thereby started writing to stdout, 
weird stuff started to happen to my shell with the python interpreter.

Apparently, there are control characters and ansi-escape codes sent from the 
process, that somehow manage to manipulate my shell if I specify an encoding. 
Consequentially the lines output with 'print(currentLine)' are reduced by these 
chars.

Is this the desired behaviour of the decoder? If so then I think this should 
potentially be further clarified in the documentation of Popen. I would have 
expected the chars to be escaped because the worst thing is, this happens even 
if you don't actually read from stdout at all. Seemingly the decoder executes 
incoming control sequences immediately (probably for the buffer?), regardless 
of if you actually bother to read the stdout or not.

The paragraph in 
https://docs.python.org/3.7/library/subprocess.html#security-considerations 
sounds like this shouldn't be happening if 'shell' is not set to 'True' at 
least.

Python for Windows

[Ana María Pliego San Martín]

Hi!

I've tried to install Python a couple of times on my computer. Although it
works fine when first downloaded, every time I turn off my computer and
then back on Python says it has a problem that needs fixing. After "fixing"
it, I still encounter some issues and have the need to uninstall it and
install it again. Do you know what the problem is?

Thank you.

Ana

The cgi.parse stdlib function works in most cases but never works when given a

 'Cause Python's import statement looks in the current directory

How to sort list of String without considering Special characters and with case insensitive

[san]

Please let me know how to sort the list of String in either ascending / 
descending order without considering special characters and case.
ex: list1=['test1_two','testOne','testTwo','test_one']
Applying the list.sort /sorted method results in sorted list ['test1_two', 
'testOne', 'testTwo', 'test_one']
but the without considering the special characters and case it should be 
['testOne','test_one', 'test1_two','testTwo'] OR 
['test_one','testOne','testTwo', 'test1_two' ]

list.sort /sorted method sorts based on the ascii value of the characters but 
Please let me knwo how do i achieve my expected one

[issue14835] plistlib: output empty elements correctly

[Sidney San Martín]

New submission from Sidney San Martín s...@sidneysm.com:

plistlib’s output is currently byte-for-byte identical to Apple’s, except 
arrays and dictionaries are stored with self-closing tags (e.g. 'array/') and 
plistlib outputs empty tags with a newline (e.g. 'array\n/array').

This tiny patch makes its output for empty arrays and dictionaries consistent 
with the OS’s.

Replacement for the shelve module?

[Forafo San]

Folks,
What might be a good replacement for the shelve module, but one that
can handle a few gigs of data. I'm doing some calculations on daily
stock prices and the result is a nested list like:

[[date_1, floating result 1],
 [date_2, floating result 2],
...
 [date_n, floating result n]]

However, there are about 5,000 lists like that, one for each stock
symbol. Using the shelve module I could easily save them to a file
( myshelvefile['symbol_1') = symbol_1_list) and likewise retrieve the
data. But shelve is deprecated AND when a lot of data is written
shelve was acting weird (refusing to write, filesizes reported with an
ls did not make sense, etc.).

Thanks in advance for your suggestions.

 Firstly, since when is shelve deprecated? Shouldn't there be a
 deprecation warning onhttp://docs.python.org/dev/library/shelve.html?

 If you want to keep your current approach of having an object containing
 all the data for each symbol, you will have to think about how to
 serialise the data, as well as how to store the documents/objects
 individually. For the serialisation, you can use pickle (as shelve does)
 or JSON (probably better because it's easier to edit directly, and
 therefore easier to debug).
 To store these documents, you could use a huge pickle'd Python
 dictionary (bad idea), a UNIX database (dbm module, anydbm in Python2;
 this is what shelve uses), or simple the file system: one file per
 serialised object.

 Looking at your use case, however, I think what you really should use is
 a SQL database. SQLite is part of Python and will do the job nicely.
 Just use a single table with three columns: symbol, date, value.

 Thomas

Sorry. There is no indication that shelve is deprecated. I was using
it on a FreeBSD system and it turns out that the bsddb module is
deprecated and confused it with the shelve module.

Thanks Ken and Thomas for your suggestions -- I will play around with
both and pick one.

TypeError: 'module' object is not callable

[Forafo San]

I wrote a class, Univariate, that resides in a directory that is in my 
PYTHONPATH. I'm able to import that class into a *.py file. However when I try 
to instantiate an object with that class like:

x = Univariate(a) # a is a list that is expected by the Univariate 
class

python raises the TypeError: 'module' object is not callable.  If I embed the 
code of the Univariate class in my *.py file, there is no problem.  Also, when 
the class is imported and I do a

print dir(Univariate)

it does not print all the methods that are in the class, while if the class 
code appears in my *.py file, all the methods are available and a list with the 
correct methods are printed.

What gives?

Thanks in advance.

 I think you mat be confusing the class with the module.
 
 When you write:
 
  import Univariate
 
 you're importing the module.
 
 If the module is called Univariate and the class within the module is
 called Univariate then you should either write:
 
  import Univariate
  x = Univariate.Univariate(a) # the class Univariate in the module 
 Univariate
 
 or:
 
  from Univariate import Univariate
  x = Univariate(a)
 
 Incidentally, it's recommended that module names use lowercase, so that
 would be:
 
  import univariate
  x = univariate.Univariate(a)
 
 or:
 
  from univariate import Univariate

Thank you all for your replies. When I do a

from Univariate import Univariate

the TypeError disappears and everything is fine.  Clearly this was an error 
that a newbie such as myself is likely to make because of little experience 
with Python. However, this isn't something I'm likely to forget.

I will also adopt the style recommendations.  Thanks, again.

Can I use python for this .. ??

[san]

Hi

I am using windows xp and have installed python and win32. I am
familiar with basic Python. I wanted to control some of the
applications via python script.

I would like to write a python script to say:
1. Open firefox and log on to gmail
2. Another firefox window to visit slickdeals
3. Open winamp and tune in to a shoutcast station
4. Open groupwise ...
etc ..

These are the task I do every day whenever I log on my computer .. it
just seems repetitive and hence probably can be coded in python.

Can I do this in python? Where do I find the COM objects/interfaces for
all these different programs? Are there any sample codes ?

Thanks.
Santosh.

Re: Can I use python for this .. ??

[san]

btw i got the firefox to open and access some webpage and winamp
running ..

code below
--
import os
import os.path
import subprocess

# Web pages
ffox_exe = r'C:\Program Files\Mozilla Firefox\firefox.exe'
assert os.path.exists(ffox_exe)
# open gmail
url = http://www.gmail.com;
child = subprocess.Popen( (ffox_exe, url), executable = ffox_exe)
rc = child.wait()

# Winamp
wamp_exe = r'C:\Program Files\Winamp\winamp.exe'
assert os.path.exists(wamp_exe)
url = http://64.236.34.97:80/stream/1040;
child = subprocess.Popen( (wamp_exe, url), executable = wamp_exe)



now is there anyway i can enter user name and password and then click
okay .. (not for gmail but for other similar webpages which require
loggin) .. ??

how to open pages in tabs .. ??

[john san]

yes. u need mod-xbox. since its be easy done and we already have OS,
Python support what we need now is only that Python can easy to coding
and show window program just like wt we can do under Windows.

  You can run Linux with MythTV on an XBox. Does all the things you want,
  and of course it will run WxPython.

 But does that involve modding the Xbox?? As in messing with the hardware??

 Are you actually still running a pure DOS machine? Or are you running
 the dos prompt through Windows?

Re: [newbie]How to install python under DOS and is there any Wxpython can be installed under dos?

[john san]

Just want to show windows under dos without MsWindows. Also find some
difficulty to simply install WxPython under directory(DOS) and then run,
which is very good thing if it is just like Java.
I want a simple solution for Python to install to DOS and then can have
Windows running.( to be used under mod-xbox which support only limited
python via using xboxmediacenter. (xbox using stripped NT OS).

 Any reason you're asking about wxPython for DOS? Just curious.

 I don't think you'll have any luck finding wxPython for DOS.  A bit of
 a looksee around the wxWidgets website (wxPython is a wrapper for
 wxWidgets) mentions being available for Win3.1 and up, as well as
 various levels of *nix installs (wxGTK, wxMotif, wxX11), but no
 mention of DOS.  I suppose that a very ambitious person could perhaps
 get the wxUniversal port to run on DOS, but I presume that this would
 be far from trivial.

 On the other hand, you probably could find and/or create some sort of
 basic text-only windowing library.  It won't be wxPython, nor anything
 even close to that level of sophistication, but that's what happens
 when you insist on using an OS that's been obsolete for a decade or
 more. ;)

pyclbr

[Fernando San Martín Woerner]

Hi guys!

i'm using pycblr to implement a class browser for my app, i got some
issues about it:

i did:

dict = pyclbr.readmodule(name, [dir] + sys.path)

but  this only works one time, i mean if module name is changed and
some class were added or removed i can't see any changes even if i
execute readmodule again.

any idea?, thanks in advance
