## Коды состояния

Вы можете определить (HTTP) `status_code`, который будет использован в ответах вашей *операции пути*.

Вы можете передать только `int`-значение кода, например `404`.

Но если вы не помните, для чего нужен каждый числовой код, вы можете использовать сокращенные константы в параметре `status`:

//// tab | Python 3.10+

```Python hl_lines="1  15"

* **`400`** and above are for "Client error" responses. These are the second type you would probably use the most.
    * An example is `404`, for a "Not Found" response.
    * For generic errors from the client, you can just use `400`.

## Response-Statuscode

Sie können den (HTTP-)`status_code` definieren, den die Response Ihrer *Pfadoperation* verwenden soll.

Sie können direkt den `int`-Code übergeben, etwa `404`.

Aber falls Sie sich nicht mehr erinnern, wofür jede Nummer steht, können Sie die Abkürzungs-Konstanten in `status` verwenden:
