You need to include the last chunk of code (from line 22 downwards) into a function called main that takes no parameters.
So, above the call to show_help() add a new method called main which takes no parameters:
def main():
Then, indent all the lines below that in one tab and you're done!
I hope that helps,
Steve.

Courses Plus Student 940 PointsThanks Steve, I see where i missed that def main() request. But it still fails, even if i indent. Is there any way that we can see where we indented incorrectly?
Steve Hunter
57,712 PointsThat's odd - how did you indent? I use the auto-indent by highlighting all the lines below main() not including that line, then using Command & ] (I'm on a Mac); Windows you can use Ctrl+] (closing square bracket).
So, you end up with:
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)
Nothing else changes.
Steve.

Courses Plus Student 940 PointsI had to restart the exercise to be able to indent it again and pass. Thanks for the help.
