Indeed not, so please skip what follows (I've surely been enough
of an annoying newbie, already!), but I've just remembered why I
wrote my program in such an awkward way. I wanted to be able to
import the type name t (StringType in this case) so that I could
simply use t.m() as the name of one of its methods [if "method"
is the correct term]; but in this case, where m is expandtabs(),
an additional parameter (the tab size) is needed; so, I used the
lambda expression to get around this, entirely failing to realise
that (as was clearly shown in the replies I got), if I was going
to use "lambda" at all (not recommended!), then it would be a lot
simpler to write the function as lambda s : s.m(), with or without
any additional parameters needed. (It didn't really have anything
to do with a separate confusion as to what exactly "objects" are.)

I'm just trying to make sure I really understand how I screwed up.
(In future, I'll try to work through a textbook with exercises.
But I thought I'd better try to get some quick feedback at the
start, because I knew that I was fumbling around, and that it
was unlikely to be necessary to use such circumlocutions.)
