(self, data, namespace=None, callback=None)
Send a message to one or more connected clients.

        This function emits an event with the name ``'message'``. Use
        :func:`emit` to issue custom event names.

        :param data: The data to send to the server. Data can be of
                     type ``str``, ``bytes``, ``list`` or ``dict``. To send
                     multiple arguments, use a tuple where each element is of
                     one of the types indicated above.
        :param namespace: The Socket.IO namespace for the event. If this
                          argument is omitted the event is emitted to the
                          default namespace.
        :param callback: If given, this function will be called to acknowledge
                         the the server has received the message. The arguments
                         that will be passed to the function are those provided
                         by the server.

        Note: this method is a coroutine.
