Question

This program will simulate buying a cup of coffee. The initial cost of a cup of coffee will be $2.00 (without adding items). This program will demonstrate a concept called parallel arrays. Parallel arrays are arrays that have the same number of items. For Python we will use lists. You will have a list that holds addingitems which will consist of a list equal to Cream, Caramel, Whiskey, Chocolate, Cinnamon and Vanilla. You will then have a parallel list of addingcosts equal to .89, .25, .59, 1.50, and 1.75. Notice each list has 5 items. .89 corresponds with Cream, .25 corresponds with Caramel, etc… You will use a loop and ask the user to enter addingitems or “XXX” to quit. If they enter addingitems that are in the addingitems list you will add the corresponding addingcosts to the order total. If the addingitems does not exist you will display a message that says, “Sorry, the add in items does not exist.” Once the user enters “XXX” the program ends and the order total is displayed. Make sure you are using proper function such as main() and some sort of function to add up your items.

Answer 1

addingItems = ["Cream", 'Caramel', 'Whiskey', 'Chocolate', 'Cinnamon']

addingCosts = [0.89, 0.25, 0.59, 1.50, 1.75]

orderList = []

totalCost = 0

print("\n")

while True:

itemName = raw_input('Enter the item name: ')

if itemName == "XXX":

print("\nALL ORDERS\n" + str(orderList) + "\n")

print("Total Price: ${}".format(totalCost))

break

elif itemName not in addingItems:

print("Sorry, the add in item does not exist.")

else:

index = addingItems.index(itemName)

orderList.append(itemName + ": $" + str(addingCosts[index]))

totalCost += addingCosts[index]
