Object-Oriented Programming in Python

Object-oriented programming (OOP) is a paradigm that organizes code around objects rather than functions. Python is an OOP language from the ground up. A class is a blueprint for creating objects. You define a class with the class keyword. Inside, you define methods (functions) and attributes (variables). The __init__ method is a special method that runs when a new object is created. It is used to set up the initial state. For example, a class Car might have attributes like make, model, and year, and methods like start() and stop(). OOP has four main concepts: encapsulation, abstraction, inheritance, and polymorphism. Encapsulation means bundling data and methods together. Inheritance lets you create a new class based on an existing one, reusing code. Polymorphism allows different classes to have methods with the same name but different implementations. Using OOP can make your code more modular and easier to understand, especially for large projects. A good beginner OOP project is to model a simple bank account system. Create a BankAccount class with methods for deposit, withdraw, and check balance. This will give you hands-on experience with classes and objects.
