Python Program For Simple Calculator

In this tutorial i am going to write a python program for basic calculation such as addition, subtraction, multiplication and division using while loop. I hope it will be informative for you.

Python Program For Simple Calculator

from os import system

while True:

    system("clear")

    print("Press 1: Addition")

    print("Press 2: Subtract")

    print("Press 3: Multiply")

    print("Press 4: Divide")

    print("Press 0: Exit")

    choice=int(input("Enter your choice:\n"))

    if choice==1:

        num1=eval(input("Enter a number:\n"))

        num2=eval(input("Enter a number:\n"))

        print("Sum = %g"%(num1+num2))

        input("Press Enter")

    elif choice==2:

        num1=eval(input("Enter a number:\n"))

        num2=eval(input("Enter a number:\n"))

        print("Difference = %g"%(num1-num2))

        input("Press Enter")

    elif choice==3:

        num1=eval(input("Enter a number:\n"))

        num2=eval(input("Enter a number:\n"))

        print("Product = %g"%(num1*num2))

        input("Press Enter")

    elif choice==4:

        num1=eval(input("Enter a number:\n"))

        num2=eval(input("Enter a number:\n"))

        print("Quotient = %g"%(num1/num2))

        input("Press Enter")

    elif choice==0:

        exit()

    else:

        print("Invalid Input\n")

        input("Press Enter")

Save file as tut1.py

To run this program, open terminal and type: python3 tut1.py

Choose any one option by selecting one number and hit Enter. Here we select 3 for multiplication, you can select any number from 0 to 4.
