Das bewirkt, dass `tags` eine Liste ist, wenngleich es nichts über den Typ der Elemente der Liste aussagt.

## Listen mit Typ-Parametern als Felder

Aber Python erlaubt es, Listen mit inneren Typen, auch „Typ-Parameter“ genannt, zu deklarieren.

### `List` von `typing` importieren

func getHosts(n int) (hosts []string, listeners []net.Listener, err error) {
	for i := 0; i < n; i++ {
		l, err := net.Listen("tcp", "127.0.0.1:0")
		if err != nil {
			if l, err = net.Listen("tcp6", "[::1]:0"); err != nil {
				return nil, nil, fmt.Errorf("httptest: failed to listen on a port: %v", err)
			}
		}
		addr := l.Addr()
		hosts = append(hosts, "http://"+addr.String())

			// If the cniListener exits, at least we should record an error log
			log.Errorf("CNI listener server exiting unexpectedly: %v", err)
		}
	}()

	context.AfterFunc(s.ctx, func() {
		if err := s.cniListenServer.Close(); err != nil {
			log.Errorf("CNI listen server terminated with error: %v", err)
		} else {
			log.Debug("CNI listen server terminated")
		}
	})
	return nil
}

## Listen von Modellen

Genauso können Sie eine Response deklarieren, die eine Liste von Objekten ist.

Verwenden Sie dafür Pythons Standard `typing.List` (oder nur `list` in Python 3.9 und darüber):

				return
			default:
				// There was error in the REST request, retry after sometime as probably the peer is down.
