simple reason - there is NO framework that is built ground up for nodejs style async programming.

Obviously there is Twisted and Tornado - but gevent or asyncio are actually the paradigms that people are using now. If there were a Flask like framework that was ground up built to leverage async (rather than bolting it on) and included all the batteries for web development.. then python would have a serious edge over node.

Tornado works in pretty much the same way as asyncio.
