python创建TCP客户端

自己瞎胡写了点东西

from socket import *from time import ctimeHOST = ''PORT = 21567BUFSIZ = 1024ADDR = (HOST, PORT)tcpSerSock = socket(AF_INET, SOCK_STREAM)tcpSerSock.bind(ADDR)tcpSerSock.listen(5)while True:    print('waiting for connection...')    tcpCliSock, addr = tcpSerSock.accept()    print( '...connected from:', addr)    while True:        data = tcpCliSock.recv(BUFSIZ)        if not data:            break        tcpCliSock.send('[%s] %s' %(ctime(), data))    tcpCliSock.close()tcpSerSock.close()from socket import *HOST = 'localhost'PORT = 21567BUFSIZ = 1024ADDR = (HOST, PORT)tcpCliSock = socket(AF_INET, SOCK_STREAM)tcpCliSock.connect(ADDR)while True:    data = raw_input('> ')    if not data:        break    tcpCliSock.send(data)    data1 = tcpCliSock.recv(BUFSIZ)    if not data1:        break    print(data1)tcpCliSock.close()
