What is "self" keyword in python ?

Hi Everyone !

Welcome to Codersarts....

Here Codersarts would provide top rated python program which help to improve your coding skills

The self is a Python keyword which represents a variable that holds the instance of an object.

In almost, all the object-oriented languages, it is passed to the methods as a hidden parameter.

Let suppose if you would working with python then , I'm sure you have come across methods that have self as their first parameter.

Need to do this?

Let's take a simple example to begin with. We have a Point class which defines a method distance to calculate the distance from origin.

Example:

class Point(object):
def __init__(self,x = 0,y = 0):
self.x = x
self.y = y
def distance(self):
"""Find distance from origin"""
return (self.x**2 + self.y**2) ** 0.5

 p1 = Point(6,8)
>>> p1.distance()

Output:

10
