Here's a simple line-based echo implementation using Twisted:

    from twisted.internet import reactor, protocol
    from twisted.protocols import basic

    class LineEcho(basic.LineReceiver):
        def lineReceived(self, line):
            print 'Received line:', repr(line)

    factory = protocol.ServerFactory()
    factory.protocol = LineEcho
    reactor.listenTCP(12345, factory)
    reactor.run()
