The function add_to_list message will not display.

This is my code but I'm not sure why it isn't showing up when I run it. TIA.

shopping_list = []

def add_to_list(): shopping_list.append(item) print("Added! List has {} item(s)".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)

Indented as it is, the "add_to_list" call is part of the "elif" code block, but no code after a "continue" will be executed.

The "add_to_list" line should not be indented, which will allow it to be executed when the continue does not run.

I did that to begin (and tried it again just now) the add_to_list still does not work.

It might help to see the code again (as it is after the change) and with Markdown formatting. Even better, make a snapshot of your workspace and post the link to it here.
