Automatically Generated Python Code from an UML diagram?

• PyUML - a Python Roundtrip Tool for Eclipse
• PyIdea: PyNSource UML & Patterns IDE for Python

Enterprise Architect is able to generate python code code from UML diagrams.
It is also able to also perform some reverse engineering, and therefore maintain the two versions (UML and python) synchronized together.

However, I have never used it in that way, except for some small tests just to see it in action. I personally find productivity in Python so high, that even if I am really satisfied with EA, I prefer it just to document the design.
