Enter 'HELP' for this help.
Enter 'SHOW' to see your current list.

1,196 Pointsit still aint working, bummer, make sure all your code is inside of functions, is all its saying as soon as i indent the show_help()?
David Stewart
1,196 Pointsjust for an update your indent worked, the code needed 2 more indents at shopping_list[] and while true: to bring them inline with the show_help() thank you for the help!

706 PointsYeah, the Refactoring exercise is a bit buggy b/c copying the block of code into "def main()" doesn't auto-indent, and the "Check work" function doesn't like 4-space indents on it (as I would do if I had written it into main() from scratch, rather than copy/paste).
