Can I use Ruby and Python together?

Is there something like JRuby but for Ruby and Python? Not that 开发者_如何学Cit would actually be useful to me, but just wondering.

If you develop for the .NET Framework Version 4.0, you can write code in IronRuby that calls methods that were written in IronPython and vice versa.

Jython

Parrot aims. Not quite sure about its progress, though.

_why was working on something called unholy, which converted ruby to Python bytecode.
