I wrote one of these for a project. The trouble is that to write functioning python code, even for just the primitives, you have to add a lot of extra scaffolding. I eventually stopped working on it since Pyjamas seemed to be doing a much more complete job (http://pyjs.org/ http://pyjs.org/). I may still write a limited one for use in creating code blocks in my project MongoAlchemy (http://mongoalchemy.org/ http://mongoalchemy.org/).
