服務端的代碼，記得要先運行服務端，否則老是報error 100053：

代碼如下：

import socket
import time
HOST = ''
PORT = 13651
BUFSIZE = 1024
ADDR =(HOST,PORT)

tcpSerSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(10)#表示最多 能連接多少個

while True:
    print 'wating for connection ...'
    tcpCliSock , addr = tcpSerSock.accept()
    print 'connecting from : %s' % str(addr)

    while True:
        data = tcpCliSock.recv(BUFSIZE)
        if not data:
            break
        tcpCliSock.send('[%s] %s' % (time.ctime(),data))
        
    tcpCliSock.close()#這個地方注意一下，是循環結束後再關掉
    print 'tcpCliSock.close()'
tcpSerSock.close()

客服端代碼：

import socket
HOST ='localhost'
PORT = 13651
BUFSIZE = 1024
ADDR =(HOST,PORT)
try:
    tcpClientSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcpClientSock.connect(ADDR)
except Exception as e:
    print e


while True:
    data = raw_input('please input the meassage send to server:')
    if not data:
        break
    print data
    try:
        tcpClientSock.send(data)
        data = tcpClientSock.recv(BUFSIZE)
    except Exception as e:
        print e
    if not data:
        break
    print data
tcpClientSock.close()

運行的結果：
