Tengo simpleUDPServer, que funciona conmultiprocesamiento.

Quiero crear una lista que contenga información sobre todos los clientes.

yo sueloGerente, pero no entiendo, cómo agregar información en la lista: necesito transferir el objeto del Administrador para manejar, pero ¿cómo? Mi camino con el nuevo atributo no funciona.

import multiprocessing
from socketserver import UDPServer, ForkingMixIn, DatagramRequestHandler
from socket import socket, AF_INET, SOCK_DGRAM
from settings import host, port, number_of_connections

class ChatHandler(DatagramRequestHandler):

    def handle(self):
        cur_process = multiprocessing.current_process()
        data = self.request[0].strip()
        socket = self.request[1]
        ChatHandler.clients.append(self.client_address) # error here
        print(ChatHandler.clients)


class ChatServer(ForkingMixIn, UDPServer):
    pass


if __name__ == '__main__':
    server = ChatServer((host, port), ChatHandler)
    ChatHandler.clients = multiprocessing.Manager().list()
    server_process = multiprocessing.Process(target=server.serve_forever)
    server_process.daemon = False
    server_process.start()

¿Cómo arreglar eso? ¡Gracias!
