create a new function named main

I don't get what's wrong here. Everything seems to be in my function.

shopping_list.py 
def show_help():
    # print out instructions on how to use the app
    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 show_list(shopping_list):
    # print out the list
    print("Here's your list:")

    for item in shopping_list:
        print(item)

def add_to_list(shopping_list, new_item):
    # add new items to our list
    shopping_list.append(new_item)
    print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
    return shopping_list

def 
  show_help()

  # make a list to hold onto our items
  shopping_list = []

  while True:
    # ask for new items
      new_item = input("> ")

    # be able to quit the app
      if new_item == 'DONE':
        break
      elif new_item == 'HELP':
          show_help()
          continue
      elif new_item == 'SHOW':
          show_list(shopping_list)
          continue
      add_to_list(shopping_list, new_item)
      show_list(shopping_list)

I already responded to your other similar question, but here's the answer:

:point_right: It looks like you moved that last line into the loop. It should be inside the function, but not indented so much as to be inside the loop.
