Object Oriented design example using inheritance in Python Standard Library, e.g. pathlib?

Question

pathlib is a typical Object Oriented design in Python Standard Library using inheritance. collections.abc is another one.

I would like know other example (better involve abstract base class and concrete sub-class) in Standard Library.

I did but I can't find other except for the 2 examples I listed. — Qiulang

In Python 3, everything is a class. See, for example, str, list, tuple, etc. — Silvio Mayolo

OK I will make my question be specific. I know what OO is but I want to know the example of inheritance. — Qiulang

@Qiulang are you interested on best OOP practices in python, or somewthing else? — anon01

I recommend two other well-written, well-designed, and easy-to-understand standard library modules that one could study its OOP design (with inheritance, of course).

First one is logging. The OOP diagram is shown below:

logging is one of most widely used, pure python, and to be honest, rather simple, standard library modules so it'd be worthwhile to study its design since the module's source code is not that long, and well documented.

Second one is argparse.

Another widely used library module, implemented almost all in pure python, and quite easy to understand. However if you are looking to study its design I still recommend the former one as it is a much shorter module for you to read through.

docs.python.org/3/library/exceptions.html#exception-hierarchy exception is another example.
