What would be an alternative for SignalR in Python world?
To be precise, I am using tornado with python 2.7.6 on Windows 8; and I found sockjs-tornado (Python noob; sorry for any inconveniences). But sockjs supports just 3 types of events and there are some limitations; I need things like groups, subscribers, propagating and other features that SignalR provides.
You are probably looking for Twisted, a whole real-time engine for applications. https://twistedmatrix.com/trac/
If you do microframeworks, Flask (think Sinatra on ruby) also has a real-time module, but it's all barebones really, it might not be what you're looking for:
