Getting started with Python and Telnet

Let's look at a specific Python example that implements a server that facilitates asynchronous communication.

Starting a server

Let's look at the EchoServerClientProtocol class, as follows:

import asyncio
class EchoServerClientProtocol(asyncio.Protocol):
    def connection_made(self, transport):
        peername = transport.get_extra_info('peername')

Here, our EchoServerClientProtocol class is a subclass of asyncio.Protocol. As we discussed earlier, inside...
