socketserver模块

服务器：

import socketserver
class Myserver(socketserver.BaseRequestHandler):

    def handle(self):
        while 1:
            from_client = self.request.recv(1024)   #self.request相当于conn
            print(from_client.decode('utf-8'))
            self.request.send('好'.encode('utf-8'))
        pass

if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('121.195.167.34',8002),Myserver)

    server.serve_forever()

可以开启多个客户端同时连接
