I've really only used Rational Rose, but that tool is
really limited in both directions. Class structure to
class diagrams work both ways (not for Python, but for
Java and C++ at least) but that's just a tiny part of
UML.

I don't expect any tool to do anything meaningful about e.g.
use case diagrams, but what about activity diagrams, sequence
diagrams, collaboration diagrams and state diagrams?

I agree that the brain is poor at such things, but I doubt
that any current tool is much better except for trivial
subsets of UML.
