Python's Magic Methods: Unleashing the Power of Dunder

Introduction

Python is known for its flexibility and expressiveness, and one of the features that makes it so powerful is its support for magic methods, also known as dunder (double underscore) methods. These special methods allow us to define how objects behave in specific contexts, enabling customizations and enhancing the functionality of our classes. In this article, we'll dive deep into the world of magic methods and explore their capabilities.
