python scoket聊天小工具

Server端代码如下：

#coding=gbk
from socket import *
import time
import threading
def answer_screen(HOST,PORT,BUFSIZE):
    ADDR = (HOST,PORT)
    tcpsersock =socket(AF_INET,SOCK_STREAM)
    tcpsersock.bind(ADDR)
    tcpsersock.listen(5)
              
    while True:
        print '正在连接...............................'
        tcpconnection,addr=tcpsersock.accept()
        print '连接从：',addr
                  
        while True:
            data = tcpconnection.recv(BUFSIZE)
            if not data:
                break
            tcpconnection.send('[%s] %s' % (time.ctime(),data))
            print [time.ctime()],':',data
                  
    tcpconnection.close()
    tcpsersock.close()
              
if __name__ == '__main__':
    answer_screen('127.0.0.1',21567,1024)

Clinet代码如下：

#conding=gbk
from socket import *
def  answer_client(HOST,PORT,BUFSIZE):
    ADDR = (HOST,PORT)
    tcpconnection = socket(AF_INET,SOCK_STREAM)
    tcpconnection.connect(ADDR)
      
    while True:
        data =raw_input('>')
        if not data:
            break
        tcpconnection.send(data)
        data = tcpconnection.recv(BUFSIZE)
        if not data:
            break
        print data
    tcpconnection.close()
if __name__ == '__main__':
    answer_client('127.0.0.1',21567,1024)
