Wat Use?

Question

Actually the __add__ method... we can simply calculate without using that method... I thought...
but Wat is the actual use by using tat method?

Answer 1

__add__ is basically special method for special works.mostly people also called these functions magic methods. Why we use this.when you want to add two objects then you use __add__ method and for subtract you use __sub__ and so on.

Like this.
class j():
def __init__(self,x):
self.x=x
def __add__(self,other):
print(self.x+other.x)

x=j(3) #this is self.x
y=j(4) #this is other.x
print(x+y) #output=7
#here you add two objects of j() class with the help of __add__ method you can't do this without add.if you don't define __add__ method then you will got error.
