Deep override

[Ryan]

I have a module I'm writing for work that has a class that inherits
from websucker.Sucker  I'm trying to override websuckers' inheritance
of webchecker.Checker.checkforhtml so it will just return 1(I want it
to download some files, not html).
I've tried different ways to name in and even tried to def it (Python
didn't like all those dotted names in a def).  Does anyone know how to
get this to work?
Thanks in advance for any insights.
