Python Network programming example (client and server)

Client clients
Copy the Code code as follows:

if __name__ = = ' __main__ ':
Import socket
Import OS
Sock = Socket.socket (socket.af_inet, socket. SOCK_STREAM)
Sock.connect ((' localhost ', 8001))
Import time
Time.sleep (2)
Sock.send (' 1 ')
Print SOCK.RECV (1024)

#os. System (' pause ')
#raw_input ()
Time.sleep (3)
Sock.close ()

Server service Side
Copy the Code code as follows:

if __name__ = = ' __main__ ':
Import socket
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! ')
