Hey guys, in this blog we will see a Python Program to Make a Simple Calculator.

Code

# Python Program to Make a Simple Calculator

while True:
    # take input from the user
    choice = input("1.Add \n2.Subtract \n3.Multiply \n4.Divide \n0.Exit \nEnter choice: ")

    # check if choice is one of the four options
    if choice in ('1', '2', '3', '4'):
        num1 = float(input("Enter first number: "))
        num2 = float(input("Enter second number: "))

        if choice == '1':
            print(num1, "+", num2, "=", num1+num2)

        elif choice == '2':
            print(num1, "-", num2, "=", num1-num2)

        elif choice == '3':
            print(num1, "*", num2, "=", num1*num2)

        elif choice == '4':
            print(num1, "/", num2, "=", num1/num2)
            
        elif choice == '4':
            break
            
    else:
        print("Invalid Input")

Output

1.Add 
2.Subtract 
3.Multiply 
4.Divide 
0.Exit 
Enter choice: 1
Enter first number: 2
Enter second number: 3
2.0 + 3.0 = 5.0

1.Add 
2.Subtract 
3.Multiply 
4.Divide 
0.Exit 
Enter choice: 4
Enter first number: 8
Enter second number: 3
8.0 / 3.0 = 2.6666666666666665

1.Add 
2.Subtract 
3.Multiply 
4.Divide 
0.Exit 
Enter choice: 0

Simply taking two numbers to perform actions on.

  • If the user inputs 1, it will perform add operation.
  • If the user inputs 2, it will perform subtract operation.
  • If the user inputs 3, it will perform a multiply operation.
  • If the user inputs 4, it will perform a divide operation.
  • If the user inputs 0, it will close the calculator.
