show_list() not defined.

https://w.trhou.se/bap9w1d3ub

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!

When 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.

So, then, just to clarify, that call doesn't simply point to method's definition, regardless of where the definition is in the code???

Correct. References are simply pointers to objects in the "namespace". So the referral is looked up on the namespace of objects. If it hasn't yet been defined it will raise an error.
