Python OOPs - Classes and Objects

Python is an object-oriented programming language.
Class is a user-defined datatype it has collection of variables and functions.
An object is an instance of a class which is used to access the members of the class.

Creating a Class in Python:

We can create class using the keyword class.

Syntax

class Data:
    def sample(self):
        print("Hello World")

Class methods must have an parameter named self.
The self parameter is used to represent the instance of the class, which used to access variables and methods that belongs to the class.

Creating an Object in Python:

We can use the class name to create an objects then access the members of the class.

Syntax

obj=Data()
obj.sample()

The following example shows, how to Create Class and objects with methods

Example

class Data:
    def get_name(self):
        self.name=input("Enter Your Name : ")
    def print_name(self):
        print("Name : ",self.name)
obj=Data()
obj.get_name()
obj.print_name()

Output

Enter Your Name : Ram
Name :  Ram
