There should be a easy way to see who names you, so that northrup would see this:
In python, all members are instance members, if created outside of the class definition, unless you specifically create them as members of the class.
class a: pass inst_a=a() inst_b=a() inst_a.memb_a=3 print inst_a.memb_a 3 print inst_b.memb_a Traceback (innermost last): File "<stdin>", line 1, in ? AttributeError: memb_a a.memb_class=5 print inst_b.memb_class 5
Hope that made any sense :-)
