python实现简单socket程序在两台电脑之间传输消息的方法

# Save as server.py 服务端代码# Message Receiverimport osfrom socket import *host = ""port = 13000buf = 1024addr = (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":    breakUDPSock.close()os._exit(0) # Save as client.py 客户端代码# Message Senderimport osfrom socket import *host = "127.0.0.1" # set to IP address of target computerport = 13000addr = (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":    breakUDPSock.close()os._exit(0)
