Question

the question is to refactor the code

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
     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
        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 = []
    add_to_list(shopping_list, new_item)

    show_list(shopping_list)
main()

Hi there,

It looks like you've moved some of the code into another function - I think that's going to throw it off. This challenge also checks to make sure all of the code is inside main(), so you shouldn't call it at the bottom (in a real program you would need to call it, but the challenge doesn't like it - it does that for you in the background when it checks your work). With challenges like this, you want to be careful to only do what it asks, and not more - the checks it performs will often fail if you do too much, or not exactly what it asks. In this case, you just need to add your "def main():" line above line 22, then indent everything beneath it by one tab. This can be done easily by selecting all of it and hitting Ctrl (or Cmd on Mac) + ] (closing square bracket).
