Loading scripting languages files at modules in Python

I need some lib开发者_如何学Goraries to run code written in JavaScript, Ruby and other scrinting languages inside my application written in Python. I don't want to use converters or local webservice as solution.

Try running interpritator in shell (node.js for JS i guess) from python and parsing results. It's impossible to create bindings to modules and functions of other interpetative language as far as I know.
