Python 3 Deep Dive Part 4 Oop

A mixin is a small class that provides specific behavior but is not meant to stand alone.

Python 3 Deep Dive: Mastering Object-Oriented Programming Object-Oriented Programming (OOP) in Python is often introduced as a simple matter of defining classes, instantiating objects, and using the self keyword. However, to truly master Python, you must look beneath the surface syntax. In Python, —including classes themselves—and the mechanics governing how these objects are created, initialized, and managed are deeply nuanced. python 3 deep dive part 4 oop
