[I snipped the explanations for brevity]

If this is a version of your code that actually fails when you run it  
(rather than being another artistic interpretation of a photograph of your  
code :-), then I'd go with Matt's analysis.  This will give you a  
NameError for fws_last_col if tracker.hasFWS() happens to return False for  
all students.
