1.服务端

#!/usr/bin/env python
from socket import *
from time import ctime

HOST = ''
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST,PORT)

udpSerSock = socket(AF_INET,SOCK_DGRAM)
udpSerSock.bind(ADDR)

while True:
    print 'waiting for message...'
    data,addr = udpSerSock.recvfrom(BUFSIZ)
    udpSerSock.sendto('[%s] %s' % (ctime(),data),addr)
    print '...received from and returned to :',addr

udpSerSock.close()

2.客户端

#!/usr/bin/env python
from socket import *

HOST = 'localhost'
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST,PORT)

udpCliSock = socket(AF_INET,SOCK_DGRAM)

while True:
    data = raw_input('> ')
    if not data:
        break
    udpCliSock.sendto(data,ADDR)
    data,ADDR = udpCliSock.recvfrom(BUFSIZ)
    if not data:
        break
    print data

udpCliSock.close()
