PyNSource: "A reverse engineering tool for Python source code
A python code scanner and UML modelling tool that generates
UML diagram models that you can layout, arrange and print out.
UML text diagrams, which you can paste into your source code for documentation purposes.
Java or Delphi code (which can be subsequently imported into more sophisticated UML modelling tools, like Enterprise Architect or ESS-Model (free).)"
No recoding to Python though. to java is supported, maybe there's a translation tool somewhere: java to python?
