* `items_t` değişkeni sırasıyla `int`, `int`, ve `str` tiplerinden oluşan bir `tuple` türündedir .
* `items_s` ise her öğesi `bytes` türünde olan bir `set` örneğidir.

#### `Dict`

Bir `dict` tanımlamak için virgülle ayrılmış iki parametre verebilirsiniz.

İlk tip parametresi `dict` değerinin `key` değeri içindir.

İkinci parametre ise `dict` değerinin `value` değeri içindir:
