Python: How do I type hint a filename in a function?
What is a best way in Python to hint a filename,
so that it's acceptable to pass anything into a function that you can open as a file?
Especially both strings and files found via Pathlib.
def myfunc(filename: str) -> None:
with open(filename) as f1:
# do something here
python-3.x type-hinting

I think what you are looking for is Structural Typing, which is not yet supported. It is proposed in PEP 544.
In the mean time, you could do a half-way effort by annotating with Union[str, bytes, PathLike].
