[Zope] Getting an object indirectly in a PythonMethod

[Jay, Dylan]

I have a python method as part of a ZClass. I want this method to return an
object whose id is stored in a ZClass property. In DTML this would be as
simple as <dtml-return "_[ObjNameProperty]">
I can't figure out how to do this in a python method. Things such as
self.getattr(ObjNameProperty) don't seem to work at all.
