Question

Write a Python Program that displays repeatedly a menu as shown in the sample run below. The user will enter 1, 2, 3, 4 or 5 for choosing addition, substation, multiplication, division or exit respectively. Then the user will be asked to enter the two numbers and the result for the operation selected will be displayed. After an operation is finished and output is displayed the menu is redisplayed, you may choose another operation or enter 5 to exit the program. All the Tasks has to be defined within functions and named properly for example: addition(number1,number2) for the function that calculates the addition of number 1 and number 2. Define the menu within a function and define also a function that takes as parameters the operation and the two numbers then return the operation result by calling the appropriate defined function or invalid operation otherwise. Make sure to comment your program throughout the code. Requirements: • Appropriate variable and function names • Appropriate Data types and conversions • Correct mathematical calculations • Appropriate functions definitions and calls • Fully commented program. • Correct loop structure • Accurate output display
Sample Run:
Main Menu 1: Addition

2: Subtraction

3: Multiplication

4: Division

5: Exit

Enter a Choice: 1

#python code

def menu():
    print("Main Menu\n\
            1: Addition\n\
            2: Subtraction\n\
            3: Multiplication\n\
            4: Division\n\
            5: Exit")

    return (num1+num2)

def subtraction(num1, num2):
    return (num1- num2)

    return num1*num2

def division(num1, num2):
    if num2 == 0:
        print("Can not divide by zero..")
    else:
        return num1/num2
