Import socket# buy mobile phone = Socket.socket (socket.af_inet, socket. SOCK_STREAM) # Card Phone.bind ((' 127.0.0.1 ', 8080) # boot Phone.listen (5) # Wait for the phone link print (' Server start ... ') conn, client_addr = Phone.accept ()  # (TCP link, client_addr) print (' Link: ', conn) print (CLIENT_ADDR) # based on established links, send and receive messages Client_data = CONN.RECV ( 1024x768) print (' Client message ', Client_data) Conn.send (Client_data.upper ()) # Hang up the phone link conn.close () # Shutdown phone.close ()
