🏗️ Object-Oriented Programming (OOP)

Object-Oriented Programming is not just a coding style — it is a way of thinking. Instead of writing programs as sequences of instructions, OOP lets you model the real world directly in code: objects that have properties and behaviors, interacting with each other.

This course teaches every OOP concept from first principles using Python, then applies them to real-world problems. You will understand not just *what* each concept is, but *why* it exists and *when* to use it. We cover classes, inheritance, polymorphism, encapsulation, abstract classes, composition, magic methods, design patterns, and the SOLID principles.
