I think Guido answered this better than I could in

I seem to spend a lot of time inside functions looking over values and
figuring out what to do do with them, actions which don't involve
invoking further functions, but rather operating directly on those
values in different ways.  That's probably why the lack of
interface-based design in the Python fundamentals seems such a problem
to me (and not to others).
