Question

IN PYTHON

Menu:

1. Hotdog. ($2) 2. Salad ($3)  3. Pizza ($2) 4.Burger ($4) 5.Pasta ($7)

Write a menu-driven program for  Food Court. (You need to use functions!)

• Display the food menu to a user . 5 options
• Use numbers for the options and for example "6" to exit.
• Ask the user what he/she wants and how many of it. (Check the user inputs) AND use strip() function to strip your inputs(if needed)
• Keep asking the user until he/she chooses the exit option.

(You can pass quantity1, quantity2, quantity3, quantity4 & quantity5 to save the quantities of the orders)

• Calculate the price.
• Ask the user whether he/she is a student or a staff. There is no tax for students and 9% tax for staffs. Add the tax price to the total price.
• Display the bill to the user. The bill includes:
  • The food items
  • The quantities
  • The cost of them
  • The total before tax
  • Tax amount
  • Total price after tax

• You need to have a main function and get started from the main function.

    The name of functions also up to your design but the names should show what the functions do.

• Only display 2 decimal points when displaying all the numbers.
• Put at least two outputs  (results after you run your code) at the end of your code as a multi-line comment.
• Don't forget to put your name and a short description of your code on the top on your code.
• Don't forget to test your code with Positive and Negative Testing! (For more information see this page Testing)
• Your functions should have a docstring which is a short description about what the function is and what it does.

Answer 1

I have implemented the menu-driven application as per the given description in Python. Please find the following Code Screenshot, output, and Code.
