Python Python Basics (2015) Shopping List App Refactor

Code works but will not pass test.

I have tested this code and it works as intended. I am getting feedback that the help message is not being received which I cannot replicate.

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 main():
    # make a list to hold onto our items
    shopping_list = []
    while True:
        new_item = input("> ")
        if new_item == 'DONE':
            show_list(shopping_list)
            break
        elif new_item == 'HELP':
            show_help()
            continue
        elif new_item == 'SHOW':
            show_list(shopping_list)
            continue
        add_to_list(shopping_list, new_item)

During the refractoring a line was dropped:

show_help()

Insert as the first line in `main()

the instructions said to move everything from line 22 and below into the main function. you have everything starting from line 26. show_help() should be inside your main function

def main():
  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)
