source code:

# Program make a simple calculator

# This function adds two numbers
def add(xy):
    return x + y

# This function subtracts two numbers
def subtract(xy):
    return x - y

# This function multiplies two numbers
def multiply(xy):
    return x * y

# This function divides two numbers
def divide(xy):
    return x / y


print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")

while True:
    # Take input from the user
    choice = input("Enter choice(1/2/3/4): ")

    # 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"="add(num1num2))

        elif choice == '2':
            print(num1"-"num2"="subtract(num1num2))

        elif choice == '3':
            print(num1"*"num2"="multiply(num1num2))

        elif choice == '4':
            print(num1"/"num2"="divide(num1num2))
        break
    else:
        print("Invalid Input")
