server端

import socketif __name__ == '__main__':    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)    sock.bind(('localhost', 8001))    sock.listen(5)while True:    connection,address = sock.accept()    try:        connection.settimeout(5)        buf = connection.recv(1024)        if buf == '1':            connection.send('welcome to server!')        else:            connection.send('please go out!')    except socket.timeout:        print 'time out'    connection.close()

client端

import socketimport timeif __name__ == '__main__':    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)    sock.connect(('localhost', 8001))    time.sleep(1)    sock.send('1')    print sock.recv(1024)    sock.close()

在终端运行server.py，然后运行clien.py，会在终端打印“welcome to server!"。如果更改client.py的sock.send('1')为其它值在终端会打印”please go out!“，更改time.sleep(2)为大于5的数值，服务器将会超时。
