Python Program to Add Two Numbers

In this Python tutorial, you will learn how to write code in Python to add two numbers.

Prerequisites to Built the Program

• Python Input/Output
• Python Assignment Operator
• How to do math with Python

Python Program to Add Two Numbers

number_1 = 100
number_2= 200

addition = number_1+number_2

print("The sum of {0} and {1} is:".format(number_1,number_2),addition)

Output

The sum of 100 and 200 is: 300

Similarly, we can perform the other operation on two numbers, such as multiplication (*), division (//), floor division (//), etc. In this above example, we have created a program where both the numbers were predefined, but python also provides us input() function, which allows us to write a program where we can accept input from the user.

Sum of Two Numbers Provided by The User:

number_1 = input("Enter the First Number: ")
number_2= input("Enter the Second Number: ")

addition = float(number_1) + float(number_2)

print("The sum of {0} and {1} is:".format(number_1,number_2),addition)

Output

Enter the First Number: 124.67
Enter the Second Number: 224.987
The sum of 124.67 and 224.987 is: 349.657

Behind the Code

In this above example, we have used the input() function to accept numbers from the user, and here when we perform the addition operation, we used the float() function on both the numbers because when the python use the input() function to accept the user's input, it stores that input in the string format, but here we want numeric data, so we explicitly convert that string data into a float data type. Float represents all the numeric values, positive and negative, with decimal values.
