Hey i feel like I have the right code here but keep getting bummer try again.

I put in the main() code like it said but it's still not working ? Help would be greatly appreciated.

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()

    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)

Hi there! The only thing I see that stands out as an error is that you've forgotten a colon when defining the main function. That should be:

def main():

Also, make sure you're consistent with your indentation. What I mean by that is that a Python file will not accept both space and tab indentation in the same file. I used tabs to indent my lines and it worked fine.

Hope this helps! :sparkles:
