[New-bugs-announce] [issue32642] add support for path-like objects in sys.path

[Chris Jerdonek]

New submission from Chris Jerdonek <chris.jerdonek at gmail.com>:

This issue is to suggest enhancing sys.path to recognize path-like objects, per PEP 519.

I recently ran into an issue where a path was getting added to sys.path, but the corresponding imports weren't working as they should, even though sys.path showed the path as being present. Eventually I tracked this down to the path being a pathlib.Path object rather than a string. This wasn't obvious because Path objects appear as strings in normal debug output, etc.

The sys.path docs currently say this:

> Only strings and bytes should be added to sys.path; all other data types are ignored during import.
