Они похожи на двухсотые HTTP статус-коды (от 200 до 299), которые означают, что запрос обработан успешно.

Четырёхсотые статус-коды означают, что ошибка произошла по вине клиента.

Помните ли ошибки **"404 Not Found "** (и шутки) ?

## Использование `HTTPException` { #use-httpexception }

Для возврата клиенту HTTP-ответов с ошибками используется `HTTPException`.

### Импортируйте `HTTPException` { #import-httpexception }
