You can use hasattr(object, name), with 'name' as the name of the
public method to check. It returns True if the object responds to that
method, False otherwise.
Hope it helps :)

So I need functions to assert that a given identifier quacks like a string,
or a number, or a sequence, or a mutable sequence, or a certain class, or so
on. (On the class check: I know about isinstance, but that's contrary to
duck-typing -- what I would want that check to do instead is verify that
whatever object I have, it has the same public (non-underscore) methods as
the class I'm claiming.)

Are there any standard methods or idioms for doing that?
