Python Python Basics (2015) Shopping List App Refactor

Creating a new function to organise in Py

Hi with the code I've written i cant seem to find what i have done wrong. I think i have probably over looked something. Thanks

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)

After you added the definition line for "main" it looks like you indented the next line after it, But the instructions say to *"Move everything from line 22 (show_help()) and below into your new function.", so that means you still need to indent every other line from there down.

You can quickly indent a bunch of lines by highlighting them and then holding the "Ctrl" button while you type a close-bracket ("]").
