Python Python Basics (2015) Shopping List App Refactor

I am pretty sure that I am following the directions to the T. It seems like the code editor doesn't indent right

I copy and paste all of the code into a new function named main. The code editor doesn't preserve the indentation however, and seems intent on keeping everything indented as if it wasn't inside of the function. How do I work around this, especially since when I press TAB it seems to not always give the same ammount of spaces. Is this a bug in the TH interface or am I an idiot

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)

You can't I think, just double tab as it seems as if you have 4 spaces on your indents but default for challenges are 2, indent twice for unindented things.

Ok. I fiddled with the indents, and it liked the code more this time. Thanks
