The library requires at least python 3.6.
This example creates a server that prints messages and the connection object that received the message out to the console.
Running this script will open a web-socket accepting connections on all ips on port 80. You can test it by open the file client/index.html in your browser. The HTML-file simply opens a web-socket using the jquery library. You can then send text-messages through the text-field.
The test_server-script can be run the command python3 test_server.py.
