How to call method of another class in your class in Python
By Prakash RajIn this tutorial, I am gonna show you how to access the method of another class from your class or child class by using dot(.) operator.
Call method from another class in a different class in Python
we can call the method of another class by using their class name and function with dot operator.
for Example:-
if the 1st class name is class A and its method is method_A
and the second class is class B and its method is method_B
then we can call method_A from class B by following way:
class A:
method_A(self):
{}
class B:
method_B(self):
A.method_A() (like this ....)
{}
Details:
A: class name
.: dot operator
method_A(): method of class A.
now I am gonna create a 1st parent class which has a method name sum which will return the sum of 2 nos.
#create parent class whose method is called by your class
class parent:
def sum(self,a,b):
return a+b
now I am going to create another class from there we will call sum method of a parent class.
class your_class:
def Fun(self,a,b):
self.a=a
self.b=b
'''
we can call method of another class
by using their class name and function with dot operator.
'''
x=parent.sum(self,a,b)
print("sum=",x)
Complete code in a single window:
Python program to call a method from another class
#create parent class whose method is called by your class
class parent:
def sum(self,a,b):
return a+b
class your_class:
def Fun(self,a,b):
self.a=a
self.b=b
'''
we can call method of another class

'''
x=parent.sum(self,a,b)
print("sum=",x)
#class object of child class or
ob=your_class()
x=int(input("enter 1st no."))
y=int(input("enter 2nd no."))
#fuction call of your class
ob.Fun(x,y)
Output:
enter 1st no.6 enter 2nd no.5 sum= 11
