For Python >= 3.6, urllib.request.urlretrieve() can accept argument filename= str or pathlib.Path, this Pull Request is intended to allow type checkers to acknowledge this fact.

This was prompted by MyPy 0.600 giving error:

error: Argument 2 to "urlretrieve" has incompatible type "Path"; expected "Optional[str]"

when passing a pathlib.Path filename.

Can you add a version check if sys.version_info >= (3, 6): and allow os.PathLike[str] instead of just pathlib.Path?

Thanks, and when I copy these changes into my own Python install, the original error message is no longer issued for my own .py code.
