[New-bugs-announce] [issue44270] shutil.which: does not find path/cmd.ext where ext is not given

[Michael Hirsch, Ph.D.]

New submission from Michael Hirsch, Ph.D. <michael at scivision.dev>:

The early short-circuit logic in shutil.which() when cmd includes a directory component incorrectly gives None on Windows if the correct filename suffix was not also given.

Example: on Windows if ./foo.exe exists, then shutil.which('./foo.exe') returns None.
