NameError: name 'results' is not defined

AND

Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

So I'm trying to get both the right answer (91.-something) and also define results? I thought I did already, but if someone could help me with this, I'd appreciate it! Thanks!
