Class and Object in Python

Introduction:

• In Python, a class is a blueprint for creating objects. It defines a set of attributes and methods that the objects created from the class can use. An object is an instance of a class, containing the data and behavior defined by the class.

What is a Class?

• A class is a user-defined data type that acts as a blueprint for objects. It can have attributes (data) and methods (functions) that define its behavior. The class keyword is used to create a class in Python.

Key Points:

Class Definition:  Use the class keyword to define a class.

Constructor:  Python uses the __init__() method as a constructor to initialize object attributes.

Inheritance:  All classes in Python inherit from the base class object by default.

No Constructor Overloading: Python does not support multiple constructors (constructor overloading) in a class.

What is an Object?

• An object is an instance of a class. When a class is defined, no memory is allocated until an object of that class is created. Objects represent specific data and can call the methods defined in their class.

Example of Class and Object in Python :

Here is a simple example that demonstrates how to create a class and an object in Python:
