My code doesn't show how many items are in the list or what the items are. Can anyone see what I am missing?

shopping_list = []

def show_help():
    print("What should we pick up at the store?")
    print(""" 
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help.
Enter 'SHOW' to see your current list.
""")

def add_to_list(item):
    shopping_list.append(item)
    print("Added! List has {} items.".format(len(shopping_list)))

def show_list():
    print("Here's your list:")
    for item in shopping_list:
        print(item)

show_help()
while True: 
    new_item = input("> ")

    if new_item == 'DONE':
        break
    elif new_item == 'HELP':
        show_help()
        continue

    elif new_item == 'SHOW':
        show_list()
    continue

    add_to_list(new_item)

show_list()
