In this tutorial, we will discuss Python program to add two number using function

In this topic, we will learn a simple concept of how to add two numbers using the function in the Python programming language

already we learned the same this concept using the operator in a simple way.

Program 1

Add two integer number using the function

#Python program to add two numbers using function def add_num(a,b):#function for addition     sum=a+b;     return sum; #return value num1=25  #variable declaration num2=55 print("The sum is",add_num(num1,num2))#call the function

When the above code is compiled and executed, it produces the following results

The sum is 80

Add two integer number using the function – get input from the user

Program 2

#Python program to add two numbers using function def add_num(a,b):#function for addition     sum=a+b;     return sum; #return value num1=int(input("input the number one: "))#input from user for num1 num2=int(input("input the number one :"))#input from user for num2 print("The sum is",add_num(num1,num2))#call te function

When the above code is compiled and executed, it produces the following results

input the number one: 34 input the number one: 45 The sum is 79

This is the program asked input from user two numbers and displays the sum of two numbers entered by the user

We can use pre-defined python function input() to takes input from the user. Input() function returns a string value. So we can use int() function to convert from string to int data type (shown in line 6 and 7).

Add two floating point number using the function

Program 3

#Python program to add two numbers using function def add_num(a,b):#function for addition     sum=a+b;     return sum; #return value num1=2.456 #variable declaration num2=55.54 print("The sum is",add_num(num1,num2))#call te function
the sum is 57.996

Add two float numbers using the function – get input from the user

#Python program to add two numbers using function def add_num(a,b):#function for addition     sum=a+b;     return sum; #return value num1=float(input("input the number one: "))#input from user for num1 num2=float(input("input the number one: "))#input from user for num2 print("The sum is",add_num(num1,num2))#call te function
input the number one: 34.4 input the number one: 32.45 The sum is 66.85

This is the program asked input from user two numbers and displays the sum of two numbers entered by the user

We can use pre-defined python function input() to takes input from the user. Input() function returns a string value. So we can use float() function to convert from string to float data type (shown in line 6 and 7).
