You've got 2 attributes called 'quality'. One is a method that is defined on
the class, the other a piece of data later defined on the student object itself
at init time. The second one will override the method, hiding it. Python does
not make a difference between behaviour attributes (methods) and state ones
(data), so you cannot have a method called like a piece of data.
Anyway, in your case the method is an *action* that sets and prints out an
attribute, so its name should reflect this fact.
