I don't have the cv2 module installed here so I cannot give you
a definitive answer.

But I can demonstrate to you how to investigate further.
I will use the 're' module as an example of how to locate
the file that contains the code of the 're' module.

$ python3
Python 3.7.3 (default, Jul 25 2020, 13:03:44)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import re
>>> re.__file__
'/usr/lib/python3.7/re.py'
>>>

The file you find for cv2 might be python code, or it might not.

You can investigate this by running another command as
follows (run it in your command shell eg bash, not in
your python shell).

$ file /usr/lib/python3.7/re.py
/usr/lib/python3.7/re.py: Python script, ASCII text executable

Let us know what you find.
