Classes and Objects in Python

Python is an object-oriented programming language. What this means is we can solve a problem in Python by creating objects in our programs. In this tutorial we will discuss OOPs terms such as class, objects, methods etc.


An object is an entity that has attributes and behaviour. For example, Ram is an object who has attributes such as height, weight, color etc. and has certain behaviours such as walking, talking, eating etc.


A class is a blueprint for the objects. For example, Ram, Shyam, Steve, Rick are all objects so we can define a template (blueprint) class Human for these objects. The class can define the common attributes and behaviours of all the objects.


As we discussed above, an object has attributes and behaviours. These behaviours are called methods in programming.

Example of Class and Objects

In this example, we have two objects Ram and Steve that belong to the class Human

Object attributes: name, height, weight

Object behaviour: eating()

Source code

class Human:

    #instance attributes

    def __init__(self, name, height, weight): = name

        self.height = height

        self.weight = weight

    #instance methods (behaviours)

    def eating(self, food):

        return “{} is eating {}”.format(, food)

#creating objects of class Human

ram = Human(“Ram”, 6, 60)

steve = Human(“Steve”, 5.9, 56)

#accessing object information

print(“Height of {} is {}”.format(, ram.height))

print(“Weight of {} is {}”.format(, ram.weight))


print(“Weight of {} is {}”.format(, steve.height))

print(“Weight of {} is {}”.format(, steve.weight))

print(steve.eating(“Big Kahuna Burger”))


Height of Ram is 6

Weight of Ram is 60

Ram is eating Pizza

Weight of Steve is 5.9

Weight of Steve is 56

Steve is eating Big Kahuna Burger
