Python's TCP socket programming details and simplicity

Python TCP Socket programming detailed

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

Server:

#!/usr/bin/env python #-*-coding:utf-8-*-  Import Socket import Threading import Time  def tcplink (sock, addr): C4/>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 socket  s = socket.socket (socket.af_inet, socket. SOCK_STREAM); S.connect ((' 127.0.0.1 ', 9090)); Print (S.RECV (1024x768). 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 ();
