The "HELP" option, don't show at the beginning!

If I start my Code, the HELP option, don't show at the beginning. It start immediately with that ">". The HELP option just show up, when I write it. I think, I have the same Code, then Craig.

shopping_list = []

def add_to_list(item):
  shopping_list.append(item)

  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
  add_to_list(new_item)"""

When you call a method (like "show_help"), you must put parentheses after the method name even if it does not require any arguments.

It works when you ask for it because the second one does have the parentheses.

Yes, so your line that says "show_help" before the while loop needs parenthesis after it to call it, like this:

show_help()
