In this video, we explore Python magic methods (also called dunder methods) and understand how they work behind the scenes. You will learn why methods like init, str, repr, and add exist and how Python automatically calls them to make objects behave like built-in types.

This lesson explains how dunder methods allow your custom classes to support printing, addition, comparison, length checking, and even function-like behavior. If you want to write clean, Pythonic, and professional object-oriented code, this video is essential.
