Python Program to Add Two Numbers

Here you will get the simplest way to add two numbers in python by using the + operator. The program will first ask the user to enter two numbers, calculate their sum, and finally print it.

input() is an inbuilt function that is used to take input from the user.

Example 1: Without Using Function

In this example, we do not define any function. We are directly adding the numbers and then printing the result.

a = int(input("enter first number: "))
b = int(input("enter second number: "))

sum = a + b

print("sum:", sum)

Output

enter first number:5
enter second number:7
sum: 12

Example 2: Using Function

In this example, we will create a user-defined function sum(). It will take two numbers as arguments and return their sum.

def sum(n1,n2):
  return n1+n2

a = int(input("enter first number: "))
b = int(input("enter second number: "))

print("sum:", sum(a, b))

Output:

enter first number: -4
enter second number: 5
sum: 1
