How to find "os" module file path in Python3.11 without importing it?

Question

I can get the path of 'os.py' like this:

import os
os.__file__

But how can I get it without importing it? I found this relevant question, but none of these work for Python3.11 , although they work for Python<=3.10 .

It seems that the newly introduced Python3.11 optimizations (doc) broke these solutions.

This works for me (though it seems that resolve_name actually imports the module):

>>> osp = pkgutil.resolve_name("os")
>>> osp.__file__
'/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/os.py'

or

>>> from importlib.util import find_spec
>>> spec = find_spec('os')
>>> spec.loader_state.filename
'/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/os.py'

It seems that you're using Python3.10, not 3.11 – tamuhey Feb 10 '23 at 11:22

"though it seems that resolve_name actually imports the module" - well, yes; that `__file__` attribute is coming *from a `module` object*. The second method would certainly work *after* the module was imported by the first method; does it work separately, though? – Karl Knechtel Feb 10 '23 at 12:20
@KarlKnechtel it does – Yevhen Kuzmovych Feb 10 '23 at 12:32
