Gəlin əvvəlki nümunəyə qayıdaq və **FastAPI**-nin nələr edəcəyinə nəzər salaq:

* `GET` və `PUT` sorğuları üçün `item_id`-nin <abbr title="Yol: Path">yolda</abbr> olub-olmadığını yoxlayacaq.
* `item_id`-nin `GET` və `PUT` sorğuları üçün növünün `int` olduğunu yoxlayacaq.
    * Əgər `int` deyilsə, səbəbini göstərən bir xəta mesajı göstərəcəkdir.
