Python Program to Add Subtract Multiply and Divide two numbers

In this tutorial, we will write a Python program to add, subtract, multiply and divide two input numbers.

Program to perform addition, subtraction, multiplication and division on two input numbers in Python

In this program, user is asked to input two numbers and the operator (+ for addition, – for subtraction, * for multiplication and / for division). Based on the input, program computes the result and displays it as output.
To understand this program you should know how to get the input from user and the basics of if..elif..else statement.

# Python program to perform Addition Subtraction Multiplication
# and Division of two numbers

num1 = int(input("Enter First Number: "))
num2 = int(input("Enter Second Number: "))

print("Enter which operation would you like to perform?")
ch = input("Enter any of these char for specific operation +,-,*,/: ")

result = 0
if ch == '+':
    result = num1 + num2
elif ch == '-':
    result = num1 - num2
elif ch == '*':
    result = num1 * num2
elif ch == '/':
    result = num1 / num2
else:
    print("Input character is not recognized!")

print(num1, ch , num2, ":", result)

Output 1: Addition

Enter First Number: 100
Enter Second Number: 5
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: +
100 + 5 : 105

Output 2: Division

Enter First Number: 20
Enter Second Number: 5
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: /
20 / 5 : 4.0

Output 3: Subtraction

Enter First Number: 8
Enter Second Number: 7
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: -
8 - 7 : 1

Output 4: Multiplication

Enter First Number: 6
Enter Second Number: 8
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: *
6 * 8 : 48
