Python Introducing Lists Build an Application Add Items

No error message but not getting the Added! List has x items....

#create a new shopping list
shopping_list = []

#create function named add_to_list that declares a parameter named item
def add_to_list(item):
    #add item to list
    shopping_list.append(item)
    #notify the user the item is added. Show the user the number of items in the list
    print("Added! List has {} items.".format(len(shopping_list)))

def show_help():
    print("What should pick up at the store?")
    print("""
Enter 'DONE' to stop addding on the list.
Enter 'HELP' for this help.
""")

#user can type done to end the list using the break method
show_help()
while True:     #infinite loop
    new_item = input("> ")
    if new_item == "DONE":
          break     #ends infinite loop
    #user can ask for help
    elif new_item == "HELP":
          show_help()
          continue     #continues loop

Looks like the call to add item is outside the while loop. Increase the indentation 4 spaces so it follows the if statement within the while block.

Post back if you need more help. Good luck!!!

Got it. Thanks for the help!
