If that's true, then my dbobj Python package
(www.valdyas.org/python/dbobj.html) will do just as well. This
allows you to map tables to Python objects; you can even subclass
the resulting objects to add extra methods. It's used in kura
(www.valdyas.org/linguistics/index.html), and the version included in
that application is a bit more advanced.
