Why does it keep telling me that the show_list() method call on line 29 of shopping_list_2.py is undefined? The def looks good to me. What am I missing? Thanks in advance!

Treehouse Moderator 68,441 PointsWhen parsing your code for the first time, line 29 references show_list() before it is defined on line 38. Move the show_list() definition into the beginning of the code. it's also a good practice to place all function definitions before regular code.
