Object-Oriented Programming in Python Cheatsheet

A class is a blueprint, an instance is the object built from it, and a small set of tools, methods, inheritance, and dunder methods, defines how that object behaves. This cheatsheet gathers the whole toolkit on one page, each snippet annotated line by line. Keep it open while you code, or save the image and pin it nearby.

For the full background, read the guide to object-oriented programming in Python. To practise, work through the 10 code-along examples.
