In a sense, classes serve as a template to create objects. They provide the characteristics and operations that the objects will employ. Suppose a class is a prototype of a building.

2. In Python, every object has its unique state. We give each object its unique state by creating attributes in the __init__method of the class. Example: Number of doors and seats in a car. 3.
