Good day, tell me, I set myself the task of writing a full-fledged chat in python, where to start? what kind of literature to read on certain topics? blogs, videos, etc. and in general how to think over and build architecture? thanks in advance, sorry if I'm not asking questions clearly, newbie, and yes about web sockets, if nevertheless tell me good literature on them, and preferably in Russian, I learn English but not so good yet, and I write in python 3.

Answer 1

look at tornado + socks.js

Answer 2

from a RabbitMQ installation

Answer 3

For a beginner, I would recommend NOT to use asynchronous frameworks, message queues, websockets.
Start with the simplest: Flask + PostgreSQL / MySQL.
