You really gave it your all on this one. Next time post what little/incorrect code you have and we'll help you along.

def show_help():
    # print out instructions on how to use the app
    print("What should we pick up at the store?")
    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:

def add_to_list(shopping_list, new_item):
    # add new items to our list
    print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
    return shopping_list

def main():

# 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':
        elif new_item == 'HELP':
        elif new_item == 'SHOW':
        add_to_list(shopping_list, new_item)

OK, Im just very new to all this. And for me to tell where I should call a function or not is difficult. For example the code you gave doesnt work when copied and pasted into workspaces. And I also ran the code commenting out the calling of show_help() and the code still worked.

Thanks for posting though. Inside the challenge the code you gave clears.

Your comment indicates that something inside of your workspaces is probably incorrect.

It is saying make sure that all your code is inside the function. What could be the problem
