Anthony Sottile added the comment: sure, it's the standard PATHEXT (basically a fresh vm from modern.ie) -- the only reason I noticed this is I was reading the source: https://github.com/python/cpython/blob/5bbac8cbdf140ebce446ea4e7db2b20a5d7b8402/Lib/shutil.py#L1367-L1373 C:\Users\IEUser>

Eryk Sun added the comment: In a patch review [1] for issue 24505, I had a discussion with Toby Tobkin about extending the behavior of shutil.which() on Windows. This was to match the behavior of the CMD shell, including securing the search path via NeedCurrentDirectoryForExePath, searching

Steve Dower added the comment: It certainly doesn't match "which" semantics, but given the F_OK and X_OK flags I can see cases where it ought not to. I'm not sure it does what it implies for those either though. I can see uses for "find files according to 'which'" and "find executable files

Ryan McCampbell added the comment: This is how windows looks up commands, as well as the built in "where" command. (Note that windows doesn't actually distinguish between "executable" files and just plain old files, so this could be confusing for UNIX users... a text file for instance will s

Karthikeyan Singaravelan added the comment: I am adding windows as a component during triaging since PATHEXT seems to be windows specific. Unfortunately, I couldn't verify this since I don't have windows system to check this against master so leaving it to 3.6. Thanks -- components:

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

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 sho
