none, you'd have to do that separately.

If you're thinking JSON, then I think you'd want text, not binary. Maybe 
you can make use of the repr()?

It wouldn't be hard to just right your own text renderer from scratch, 
unless you need C speed. Python being python, I'd tend to see what your 
Java (or Javascript) code can easily consume, then write the python code 
to generate that.

Does JSON have a representation for n-d arrays? In my little work with 
it, it looked pretty lame for arrays of number, so I'd be surprised.
