An echo server so I remember how to use sockets.

gistfile1.py

import socket


def main():
    server = socket.socket()
    server.bind(('localhost', 9999))
    server.listen(1)
    print 'listening on :9999'
    client = server.accept()[0]
    while 1:
        msg = client.recv(1024).strip()
        print msg
        if msg == 'die':
            client.close()
            server.close()
            break


if __name__ == '__main__':
    main()
