python开发简单socket程序在两台电脑之间传输消息，分为客户端和服务端，分别在两台电脑上运行后即可进行简单的消息传输，也可以在一台电脑上测试，设置两个不同的端口即可。

# Save as server.py 服务端代码 - sharejs.com  # Message Receiver  import os  from socket import *  host = ""  port = 13000  buf = 1024  addr = (host, port)  UDPSock = socket(AF_INET, SOCK_DGRAM)  UDPSock.bind(addr)  print "Waiting to receive messages..."  while True:      (data, addr) = UDPSock.recvfrom(buf)      print "Received message: " + data      if data == "exit":          break  UDPSock.close()  os._exit(0)     # Save as client.py 客户端代码 - sharejs.com  # Message Sender  import os  from socket import *  host = "127.0.0.1" # set to IP address of target computer  port = 13000  addr = (host, port)  UDPSock = socket(AF_INET, SOCK_DGRAM)  while True:      data = raw_input("Enter message to send or type 'exit': ")      UDPSock.sendto(data, addr)      if data == "exit":          break  UDPSock.close()  os._exit(0)
