[issue38946] IDLE not opening multiple .py files

[Ramon]

New submission from Ramon :

I'm running Python 3.8 and Mac Os Catalina 10.15.1 When I click a .py file, it 
will open the shell + editor, However if I try to open a new .py file from my 
finder window it won't open. The only way I can open another file is through 
the shell by clicking file - open. I downloaded a folder with containing .py 
files from the web and I have no issue opening those files from my finder 
window. It appear to be only files created in my computer.

[issue42991] support for splitting multichannel audio fragments in audioop module

[Ramon]

New submission from Ramon :

All functions from the audioop module that work on stereo fragments, provide 
the same behaviour on multichannel (i.e. 5.1 channel LPCM) fragments. This is, 
however, not true for the tomono() function, that only makes sense when 
supplied with a 2-channel fragment.

Therefore, I suggest adding an extra function to the module that demultiplexes 
any N-channel fragment and returns a given channel as mono fragment:
audioop.demux(fragment, width, nChannels, channel)

When, for example, applied to a 16 bit stereo fragment, audioop.demux(fragment, 
2, 2, 0) would give the same result as audioop.tomono(fragment, 2, 1.0, 0).

[issue3502] Inconsistency between string.letters and default encoding.

[Ramon Garcia]

New submission from Ramon Garcia <[EMAIL PROTECTED]>:

In python on Windows, under Idle, the string.letters includes extended
characters. But the default codec, used when translating from string to
unicode, is still ascii. This behaviour causes crashes with python win32
extensions.

>>> string.letters

'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\x83\x8a\x8c\x8e\x9a\x9c\x9e\x9f\xaa\xb5\xba\xc0\xc1\xc2\xc3\xc4\xc5\xc6\xc7\xc8\xc9\xca\xcb\xcc\xcd\xce\xcf\xd0\xd1\xd2\xd3\xd4\xd5\xd6\xd8\xd9\xda\xdb\xdc\xdd\xde\xdf\xe0\xe1\xe2\xe3\xe4\xe5\xe6\xe7\xe8\xe9\xea\xeb\xec\xed\xee\xef\xf0\xf1\xf2\xf3\xf4\xf5\xf6\xf8\xf9\xfa\xfb\xfc\xfd\xfe\xff'

But still, unless the user customizes the installation,
sys.getdefaultencoding() returns ascii.

The consequence is that after instating a COM object, pywin32 211 issues
this exception:

  File "C:\Python25\Lib\site-packages\win32com\client\build.py", line
297, in MakeFuncMethod
return self.MakeDispatchFuncMethod(entry, name, bMakeClass)
  File "C:\Python25\Lib\site-packages\win32com\client\build.py", line
318, in MakeDispatchFuncMethod
s = linePrefix + 'def ' + name + '(self' + BuildCallList(fdesc,
names, defNamedOptArg, defNamedNotOptArg, defUnnamedArg, defOutArg) + '):'
  File "C:\Python25\Lib\site-packages\win32com\client\build.py", line
604, in BuildCallList
argName = MakePublicAttributeName(argName)
  File "C:\Python25\Lib\site-packages\win32com\client\build.py", line
542, in MakePublicAttributeName
return filter( lambda char: char in valid_identifier_chars, className)
  File "C:\Python25\Lib\site-packages\win32com\client\build.py", line
542, in 
return filter( lambda char: char in valid_identifier_chars, className)
UnicodeDecodeError: 'ascii' codec can't decode byte 0x83 in position 52:
ordinal not in range(128)



The line that causes this exception is from win32com.client.build.

This fragment is enough to reproduce the bug (from build.py in
win32com/client):

valid_identifier_chars = string.letters + string.digits + "_"
...
return filter( lambda char: char in valid_identifier_chars, className)

Try to print the expression in the return statement and set className to
anything you wish in Unicode. It will crash

It is contradictory that the default codec does not allow translation of
characters  0x83, and that string.letters includes it. If one regards
this character as printable, then it should be encoded successfully.

[issue39063] Format string does not work with "in" statement

Tried to use "in" statement to check if a string exists in a array and failed 
using string format.

How to reproduce:

In [4]: z = "a"

In [5]: f"{z}" in ["a", "b"]
Out[5]: True

In [6]: z = "b"
