Hi Dmitry, I'll write out the steps required to complete this challenge. If you are still having trouble, leave a comment.

  1. On line 22 create a new function, call it main, it accepts no arguments.
  2. Select everything from line 23 to the end of the code, and indent it so that it is now inside your newly created function.

it is exactly what i am doing , still doesn't work

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)

Don't forget to make sure that everything is indented, so that it is inside the main function :)

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)

Edit, sorry it may just be the extra space you have in def main() : that is causing the problem. Just remove that if the indentation is fine.
