#简易 UDP 客户端




import socket


target_host = "127.0.0.1"#本机回送地址（Loopback Address
target_port = 10000


#build a socket object
client = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)#UDP
#send some data
while 1:
    data = raw_input()
    client.sendto(data,(target_host,target_port))
#receive some data
data,addr = client.recvfrom(4096)#4k


print data

UDP服务端 参考http://www.jb51.net/article/49357.htm

#!usr/bin/env python
#-*- coding: utf-8 -*-

import socket

target_host = '127.0.0.1'
target_port = 10000

server = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
server.bind((target_host,target_port))

while 1:
    data,addr = server.recvfrom(4096)#4k
    if not data:
        break
    print "receive data from",addr
    print data

server.close()
