В таких случаях обычно возвращается **HTTP-код статуса ответа** в диапазоне **400** (от 400 до 499).

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`
