[New-bugs-announce] [issue31405] shutil.which doesn't find files without PATHEXT extension on Windows

[Ryan McCampbell]

New submission from Ryan McCampbell:

On windows, shutil.which does not match the semantics of built-in command lookup. If you pass the name of a script like foo.py and the PATHEXT variable doesn't include .py it will search for foo.py.exe, foo.py.bat, foo.py.cmd, etc. but not foo.py, which should be the first name checked.
