Calculator Program In Python

We are presenting you with one of the shortest and simplest calculator programs in python you could ever found. This calculator will contain the most basic functions you have seen in your life.

We will be creating a calculator that will add, subtract, divide, and multiply two numbers.

We will run the program until we don’t want to exit using a while loop, so that we can calculate as many as calculations we want.

If you want the calculator program in python gui then click here.

First, we will ask the user to choose one of the four basic operations i.e. “Addition“, “Subtraction“, “Multiplication“, and “Division“.

print("1. Addition")
print("2. Subtraction")
print("3. Multiplication")
print("4. Division")

We will also give choice to the user so that he can exit the program whenever he wants.

print("5. Exit")

Now, we will store the value entered by the user using the variable “choice“.

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

Now, we will see the code and we will use comments to explain to you this basic Calculator Program In Python.

Calculator Program In Python: Code

# creating while loop
while True:
    # printing the available options
    print("1. Addition")
    print("2. Subtraction")
    print("3. Multiplication")
    print("4. Division")
    print("5. Exit")
    # asking user to Enter his choice
    choice = int(input("Enter your choice: "))
    # checking the choice between 1 and 4
    if (choice>=1 and choice<=4):
        # asking to enter two options
        print("Enter two numbers: ")
        # accepting first number
        num1 = int(input())
        # accepting second number
        num2 = int(input())
        # checking if number is 1
        if choice == 1:
            # adding
            res = num1 + num2
            # printing Addition
            print("Result = ", res)
        # checking if number is 2
        elif choice == 2:
            # Subtracting
            res = num1 - num2
            # printing Subtraction
            print("Result = ", res)
        # checking if number is 3
        elif choice == 3:
            # Multiplication
            res = num1 * num2
            # printing Result
            print("Result = ", res)
        # after checking all 3 choice,
        # only one operation left, i.e. for Division
        else:
            # Division
            res = num1 / num2
            # printing Result
            print("Result = ", res)
    # checking if the choice is 5
    elif choice == 5:
        # if choice is 5, we will exit the program
        exit()
    # everything, except the five choices is useless
    # so, we will print Wrong input..!!
    else:
        print("Wrong input..!!")
