There's a impedance mismatch between UML and actual programming languages. Idiomatic python is different from idiomatic java, and trying to make UML as it was originally intended, to be a detailed, formal specification of a program, is quite at odds with that. You either end-up having to ignore most 90% of the diagram, only using the high-level details, or you end up with programmatically generated garbage code.
