1.导入socketserver，ThreadingTCPServer支持多client连接

import socketserverclass Mysocket(socketserver.BaseRequestHandler): def handle(self): while True: try: pass except ConnectionResetError as e: print(e)if __name__=="__main__": Host,port='localhost',8989 server=socketserver.ThreadingTCPServer((Host, port), Mysocket) server.serve_forever()
