... they are not designed to explicitly return something else? The reason I ask is that I almost fell into the following trap:
<GCE trap> py3: a_lst = [0, 1, 2] py3: b_lst = a_lst.append(3) py3: a_lst, b_lst ([0, 1, 2, 3], None) Instead of "None" I was expecting "[0, 1, 2, 3]". Obviously I have a GCE (Gross Conceptual Error). </GCE trap> I almost sent the above as my question, but then I realized (Finally!) that lst.append() performs an append operation on lst and returns None. Just like print() returns None. So my actual question is: For these types of methods/functions, is Python Both versions 2 and 3) consistent throughout and *always* returns None?
