Introduction to Python Classes and Objects: A Beginner’s Guide

Object-oriented programming (OOP) is a popular paradigm in software development, and Python fully supports it. In OOP, we model real-world entities as objects, which makes our code more modular, reusable, and easier to manage. This guide will introduce you to the basics of classes and objects in Python.

What Are Classes and Objects?

• Class: A blueprint for creating objects. It defines a set of attributes and methods that the objects created from the class will have.
• Object: An instance of a class. It contains data (attributes) and behavior (methods) defined by the class.

Why Use Classes and Objects?

• Encapsulation: Bundles data and methods that operate on the data within one unit.
• Reusability: Allows code to be reused across different parts of a program.
• Modularity: Makes code more modular and easier to manage.

Defining a Class

To define a class in Python, use the class keyword followed by the class name and a colon. The class name should follow the CamelCase naming convention.

Syntax:

class ClassName:
    # Class body
