So far, the two libraries I've considered (considering I want to make use of Asyncio) are:
Websockets (wish they renamed their library because whenever you look up python 3 web sockets it's all you see)
Which library would you suggest as a backend for an instant messenger? Or, would you suggest not using Python at all, and going with a language more traditional, such as Node.JS? The reason I am picking Python is because I have a decent background in asynchronous programming with Python, as I have just recently developed an asynchronous socket server.
