[Tutor] Python Websocket Server

[Simon Connah]

Hi,

I was wondering what the best practice for writing web socket servers in 
Python was in 2019? I found an old example on the web which used the 
tornado library but that was talking about Chrome 22 as the client which 
is ancient now so I'm not sure if things have changed?

Any suggestions on the best library to use would be greatfully accepted. 
I'd ideally like to be able to do it in an asynchronous manner.
