Python is an object-oriented programming language, meaning it uses objects to represent data. Objects are instances of classes, which define their behavior and attributes. Mastering class definition is essential if you want to become proficient in Python. This guide will walk you through defining a class in Python, providing up-to-date code examples and practical advice.

What is a Class?

A class is a blueprint for creating objects. It defines what attributes and behaviors its instances should have. To create a class in Python, use the class keyword followed by the name of the class. By convention, class names start with a capital letter. Here's an example:
