Ardından `random.choice()` ile list’ten **rastgele bir değer** alırız; yani `(id, name)` içeren bir tuple elde ederiz. Şuna benzer: `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

Sonra tuple içindeki bu **iki değeri** `id` ve `name` değişkenlerine **atarız**.

Böylece kullanıcı bir item ID’si vermemiş olsa bile yine de rastgele bir öneri alır.
