初学脚本语言python，测试可用的tcp通讯程序：

服务器：

#!/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(1024);        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();

客户端：

#!/usr/bin/env python# -*- coding: utf-8 -*-import sockets = socket.socket(socket.AF_INET, socket.SOCK_STREAM);s.connect(('127.0.0.1', 9090));print(s.recv(1024).decode('utf-8'));for data in [b'lk', b'aa', b'bb']:    s.send(data);    print(s.recv(1024).decode('utf-8'));s.send(b'exit');s.close();
