One of the most profound concepts in advanced Python OOP is how functions transform into methods. Function vs. Bound Method

This article explores the advanced inner workings of Python OOP, covering topics such as slots, custom representations, multiple inheritance, and meta-programming, largely inspired by the comprehensive material found in the Udemy Python 3: Deep Dive (Part 4 - OOP) course. 1. Beyond the Basics: Understanding Python Object Internals
Allowing a new class (child) to inherit attributes and methods from an existing class (parent), promoting code reuse.

Python’s abc module provides the ABCMeta metaclass and the ABC helper class.
class Order: quantity = PositiveNumber()
Attribute lookup in Python goes through several steps: # Forgetting perimeter() =>
Once __new__ returns the instance, Python passes that instance to __init__ as self , along with any arguments passed to the class constructor.
Metaclasses are the "classes of classes." They define how a class behaves and is constructed.
Inheritance is a fundamental concept in OOP that allows one class to inherit the attributes and methods of another class. The class that is being inherited from is called the parent or superclass, and the class that is doing the inheriting is called the child or subclass.
