Question

Simple python assignment

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

• Display the food menu to a user (Just show the 5 options' names and prices - No need to show the Combos or the details!)
• Ask the user what he/she wants and how many of it. (Check the user inputs) AND Use strip() function to strip your inputs.
• Keep asking the user until he/she chooses the end order 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.

Tax

Cupertino

9.000%

Santa Clara

• 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 can have your own design but you need to have a main function and get started from the main function.

For example:

def main():

displayMenu()

.

.

displayBill(..)

main()

or

if __name__ == "__main__":
main()

The name of functions also up to your design but they 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)

Answer 1

#Python program that display a list of items and its cost to user and then prompt user to enter his/her choice of item.
#the program prompts user to enter choice of items until user enters 0 to stop reading. Then prompt whether discount is #applied and then find the total bill, before and after tax calculation
#main.py
def main():

    #9 % tax rate for staff
    TAX=0.09
    #set constant values
    CUPERTINO_COST=5
    COFFEE=4
    SOFTDRINK=3
    COCONUT=5
    FRENCHFRIES=10
    #set zero values
    total=0
    taxamount=0
    totalbill=0
    #call getChoice function
    choice=getChoice()

    while choice!=0:
        if choice==1:
            total=total+CUPERTINO_COST
        elif choice==2:
            total=total+COFFEE
        elif choice==3:
            total=total+SOFTDRINK
        elif choice==4:
            total=total+COCONUT
        elif choice==5:
            total=total+FRENCHFRIES
        choice = getChoice()

    #Get user value for type of person
    type=int(input('Enter 1 for student or 2 for staff :'))
    if type==1:
        taxamount = 0
    elif type==2:
        #calculate the 9% tax amount on total
        taxamount = total * TAX
    #calculate total bill amount
    totalbill=total+taxamount

    #print total, tax and total bill value
    print('Cost of the items : ',total)
    print('Tax amount : ',taxamount)
    print('Total price after tax : ',totalbill)

#Function that display the items to user
def displayMenu():
    print('1.Cupertino ---5$')
    print('2.Coffe ---4$')
    print('3.Soft drink ---3$')
    print('4.Coconut ---5$')
    print('5.French-fries ---10$')
#Function that prompts for user choice
def getChoice():
    displayMenu()
    choice=int(input('Enter choice [1-5] or 0 to exit: '))
    if (choice<0 or choice>5):
        print('Invalid choice')
    else:
        return choice
#Function that calls main
if __name__ == "__main__":
    main()
