Це схоже на HTTP статус-коди 200 (від 200 до 299). Ці "200" статус-коди означають, що запит пройшов успішно.

Статус-коди в діапазоні 400 означають, що сталася помилка з боку клієнта.

Пам'ятаєте всі ці помилки **404 Not Found** (і жарти про них)?

## Використання `HTTPException`

Щоб повернути HTTP-відповіді з помилками клієнту, використовуйте `HTTPException`.

### Імпорт `HTTPException`
