in get attribute
Traceback (most recent call last):

a.testprint()
TypeError: 'NoneType' object is not callable

why is it so? __getattribute__ is called whenever an attribute or method
is called, rt? or if i set __getattribute__ , i cannot have methods in
class?
actually my aim is to trap all method calls and keep a counter which is
update whenever method called or returned. how should i go about it?
a.testprint causes __getattribute__ to be called. That method returns
None. a.testprint() is therefore None(), hence the exception.
