What is a Python Extension /u/No_Date8616 Python Education

I have heard a lot of Python extensions, extension modules, and Windows extensions. But qualifies something as an extension to Python. What criteria is to be met before for a module or library is said to be an extension to Python.

If a library or module uses shared libraries from ( ie. C, C++ ) and provides features to Python whether already provided by Python or not, does the module become an extension to Python ?

Or the module must integrate with the Python runtime and provide features not immediately provided by Python to be called an extension.

This is part of a larger quest to have a good understanding of Python and it workings.
