Beginner script Language Python, test the available TCP communication programs:


Server:

#!/usr/bin/env python#-*-coding:utf-8-*-import socketimport threadingimport timedef tcplink (sock, addr):    print (' Accept new connection from%s:%s ... '% addr);    Sock.send (b ' Welcome!!! ');    While True:        data = SOCK.RECV (1024x768);        Time.sleep (1);        If not data or Data.decode (' utf-8 ') = = ' exit ': Break             ;        Sock.send (b ' Hello,%s! '% data);    Sock.close ();    Print (' Connection from%s:%s closed. '% addr); if __name__ = = "__main__":    s = socket.socket (socket.af_inet, socket. SOCK_STREAM);    S.bind ((' 127.0.0.1 ', 9090));    S.listen (8); #监听8个客户端;    print (' Waiting for connection ... ');    While True:        sock, addr = S.accept ();        t = Threading. Thread (Target=tcplink, args= (SOCK,ADDR));        T.start ();

Client:

#!/usr/bin/env python#-*-coding:utf-8-*-import sockets = Socket.socket (socket.af_inet, socket. SOCK_STREAM); S.connect ((' 127.0.0.1 ', 9090));p rint (S.recv () decode (' Utf-8 ')); for data in [b ' lk ', b ' AA ', b ' BB ']:    s.send (data);    Print (S.RECV (1024x768). Decode (' Utf-8 '); S.send (b ' exit '); S.close ();
