My understanding, is that a single underscore is equivalent to the

That is my understanding, too. So if the method needs to be
called from classes outside of dForm, it should be 'registerObject()'
and not '_registerObject()'.
That's what I'd say.
_registerObject() should only be called from sub classes of dForm.
Where as registerObject() is part of the public interface of dForm and
can be clled from anyone.
You can take the convention strictly, like a traffic law, and make such
a rule, or you can try to sort out the intent of the convention or law
and live by that. Whenever I see a _ prefacing an identifier in Python
source code, I think "ah, this is something internal to the workings
that I'll not concern myself with". And whenever I approach the stop
sign at the corner of Monterey and B Streets, and I can see that nobody
is around, I don't come to a full and complete stop, which technically
breaks the law.
Additionally, documenting tools like epydoc have features that
automatically skip publicizing identifiers that begin with _, which sure
is handy.
