In Python, a class serves as a blueprint or a template for creating objects. It is a fundamental concept in Object-Oriented Programming (OOP), allowing you to structure your code by bundling data (attributes) and the functions that operate on that data (methods) into a single, cohesive unit.
Here's a breakdown of what a class entails:
Blueprint for Objects: A class defines the common characteristics and behaviors that objects of that class will possess. For example, a Car class might define attributes like color, make, and model, and methods like start(), stop(), or accelerate().
Encapsulation: Classes encapsulate data and the methods that operate on that data, promoting better organization and maintainability of code.
Instantiation: You create an object (also known as an instance) from a class. An object is a concrete realization of the class blueprint, with its own specific values for the attributes. For example, from the Car class, you could create an object my_car with color="red", make="Toyota", and model="Camry".
class keyword: Classes are defined in Python using the class keyword, followed by the class name and a colon.
_init_ method (Constructor): This special method is automatically called when a new object is created from the class. It's used to initialize the object's attributes.
self parameter: Within class methods, self refers to the specific instance of the object on which the method is being called. It allows you to access and modify the object's attributes and call other methods of that object.
