Und Tools werden auch glücklich sein, weil sowohl `RedirectResponse` als auch `JSONResponse` Unterklassen von `Response` sind, die Typannotation ist daher korrekt.

### Eine Unterklasse von Response annotieren

Sie können auch eine Unterklasse von `Response` in der Typannotation verwenden.

## List of models { #list-of-models }

The same way, you can declare responses of lists of objects.

For that, use the standard Python `typing.List` (or just `list` in Python 3.9 and above):

{* ../../docs_src/extra_models/tutorial004_py39.py hl[18] *}


## Response with arbitrary `dict` { #response-with-arbitrary-dict }

#### OpenAPI Ne İşe Yarar?

		logger.Fatal(err, "Unable to initialize server")

// Set of handler options as bit flags
type hFlag uint8

const (
	// this flag disables gzip compression of responses
	noGZFlag = 1 << iota

	// this flag enables tracing body and headers instead of just headers
	traceAllFlag

	// pass this flag to skip checking if object layer is available
	noObjLayerFlag
