WHAT IS PYTHON:

Python is an object oriented programming language.

Almost everything in Python is an object, with its properties and methods.

WHAT IS A CLASS:

A Class is like an object constructor, or a "blueprint" for creating objects.

Create a Class
To create a class, use the keyword class:

Example
Create a class named MyClass, with a property named x:

class MyClass:
 x = 5

WHAT IS A OBJECT:

An object is simply a collection of data (variables) and methods (functions) that act on those data. Similarly, a class is a blueprint for that object.
Create Object
Now we can use the class named MyClass to create objects:

Example
Create an object named p1, and print the value of x:

p1 = MyClass()
print(p1.x)
