错误：

OSError: [WinError 10057] En begäran att skicka eller ta emot data tilläts inte eftersom socketen inte är ansluten och (när du skickar på en datagramsocket med hjälp av ett sendto-anrop) ingen adress angavs

翻译：

Traceback (most recent call last):

OSError: [WinError 10057] A request to send or receive data was not allowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was specified

我试过了 sendall 但它没有改变一件事，我能做什么？
