<mode="screamin jay hawkins"> __getattribute__ is really some kind of an evil black voodoo mumbo jumbo juju magic method... </mode> More seriously: __getattr__() (if defined) is called when and if the 'normal' attribute lookup process failed. It's main use is to delegate attribute access to a proxied/wrapped/decorated object. __getattribute__() (if defined) completely override the attribute lookup process - so it gets full control over attribute access. This does not directly concern what you're doing now, but still, for a number of reasons, the canonical pythonic way to do named attribute access is with the builtin getattr() function, that will call on the appropriate lookup mechanism. As a general rule, '__magic__' methods are implementation, not API, so you shouldn't call on them directly unless you have a reaaaally goooood reason to do so.
