Why OOP Exists: A Clear Explanation with a Real-World Example
This article explains the core ideas behind object-oriented programming (OOP) by telling the story of a college project where the author and his friend Tito build a library management system. It shows how OOP helps represent real-world entities like books and authors, hide implementation details, and organize related functions. The article also introduces Python classes as namespaces for grouping functions, making OOP accessible even to beginners.
The core idea of OOP is that you create high-level abstractions for the entities that you care about to make it easier to work with them.
