sio.event python socketio

        Decorator to register an event handler.

        This is a simplified version of the ``on()`` method that takes the
        event name from the decorated function.

        Example usage::

            @sio.event
            def my_event(data):
                print('Received data: ', data)

        The above example is equivalent to::

            @sio.on('my_event')
            def my_event(data):
                print('Received data: ', data)

        A custom namespace can be given as an argument to the decorator::

            @sio.event(namespace='/test')
            def my_event(data):
                print('Received data: ', data)
