Bummer! Try again! Is just not helpful!!!

Been messing with this challenge and can't seem to get the right spaces they want?

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():
    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)

Hi Ian, your mistake is purely the indentation. Here is what your indents should look like:

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)

Hi Ian, It looks like you have an indentation error starting at your while loop.
