Python - Object Oriented

PYTHON OBJECT-ORIENTED

Object-oriented programming is a programming paradigm in which are based on the concept of Object. Python also supports some features of Object-oriented programming (OOP). In this post, We will learn about these features.

Python OOPS Concept

• Class
• Object
• Method
• Inheritance 

Class

In programming languages class provide a way to bundle data and functionality together. The simplest form of class definition syntax will look like

class ClassName():
    < statement - 1 >
    .
    .
    .
    < statement - n >

Example

class Calculate():
    x = 1 

Object

An object is an instance of a class. Syntax to create an object of above class Calculate is

objectName = ClassName():

Example

obj = Calculate()

We can access variable x with the syntax. 

objName.VariableName

obj.x

Method

class Calculate():
    x = 1
   
    def fun (self):
        print ('This is a method')    

Keyword self refer to an object.
To access method of a class we have to

1. Create an object of class
2. Access the method

For example in order to access fun method of Calculate class 

obj = Calculate() #Created an Object, Step 1
obj.fun()         # Accesing method, Step 2
