UML for Python or some other Graphical Notation Language

[llothar]

This is more an academic question right now but was there ever some
work in progress how UML could be made better for Python or script
languages in general.

It is so extremely deep interwoven with Java/C++ language
implementations that there are a lot of modified notiations necessary.

Or is there anything else then UML?
Eiffel still has BON for example.
