I think you've misunderstood.  __getattr__() should always be called, it
allows you to intercept and reimplement the behavior of a attribute
lookup to suit your needs.  Typically, my __getattrs__() look like this:



See:
http://docs.python.org/ref/attribute-access.html


This would lead me to think not that way...


"Note that if the attribute is found through the normal mechanism, __getattr__() is not called.  (This is an intentional asymmetry between __getattr__() and __setattr__().) This is done both for efficiency reasons and because otherwise __setattr__() would have no way to access other attributes of the instance."
