[New-bugs-announce] [issue40497] subprocess.check_output() accept the check keyword argument

[Rémi Lapeyre]

New submission from Rémi Lapeyre <remi.lapeyre at henki.fr>:

The subprocess.check_output() raises TypeError when given the `check` keyword-argument:

Python 3.8.2 (v3.8.2:7b3ab5921f, Feb 24 2020, 17:52:18) 
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.check_output(['ls'], check=False)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 411, in check_output
    return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
TypeError: run() got multiple values for keyword argument 'check'

It should just use True as the default when it's not specified in kwargs.
