# Create a new empty list called shopping_list
shopping_list = []

# Create a function named add_to_list that delcares a parameter named item
  # Add the item to the list
def add_to_list(item):
    shopping_list.append(item)
    # Notify user that the item has been added, and state the number of items in the list currently
    print("Added:list has {} items".format(len(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
  """)

show_help()

while True:
  new_item = input(">")

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

    # Call add_to_list with new_item
    add_to_list(new_item)
