1. 服务端代码如下：

   # _*_ coding:utf-8 _*_
   import socket
   import datetime
   HOST=\'0.0.0.0\'
   PORT=3434

   s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
   s.bind((HOST,PORT))
   s.listen(1)

   while True:
   conn,addr=s.accept()
   print \'Client %s connected!\'%str(addr)
   dt=datetime.datetime.now()
   message=\'Current time is\'+str(dt)
   conn.send(message)
   print "Sent:",message
   conn.close()

2. 客户端代码如下：

   import socket
   HOST=\'127.0.0.1\'
   PORT=3434
   s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
   s.connect((HOST,PORT))
   print "Connect %s:%d ok"%(HOST,PORT)
   data=s.recv(1024)
   print "Received:",data
   s.close()
