javascript execution from Python script

[Paul Rubin]

Java and javascript aren't really related, any more than "car" and "carpet".

Javascripts semantics are sort of a subset of Python's, so compiling
javascript to Python bytecode is a plausible idea that I've thought
about at times.  It would be useful for a Grail-like browser written
in Python.  I don't know of anyone ever trying to implement it though.

Yes, jython can call java code from python scripts.
