# Description:
#   This file contains python code that asks the user for
#   their grocery items, save it in a list, and prints out
#   the final list at the end.

def main():

    groceries = []
    # priming read
    item = input("What would you like to buy? ('STOP' to stop): ")

    # sentinel loop, in which we fill the list with groceries
    while item != "STOP":
        groceries.append(item)
        item = input("What would you like to buy? ('STOP' to stop): ")

    index = 0
    # go through the list and print out the contents
    while index < len(groceries):
        # this tells us which index is being printed out, as well
        print("Printing groceries at", index, ":", groceries[index] )
        index = index + 1
