The other way around does exists, python in your web browser:
http://brython.info

Did a quick iPhone web app that way and demoed it to our local Python
group last night:

You could easily extend this concept where your python script server
side controls your python script client side through reverse Ajax. And
of course it's also possible to do the whole thing client side,
without a server. Works on all modern browsers too.
