Bu durumda, fonksiyon parametresi `q` isteğe bağlı olur ve varsayılan olarak `None` olur.

/// check | Ek bilgi

Ayrıca, **FastAPI** path parametresi olan `item_id`'nin bir path parametresi olduğunu ve `q`'nun path olmadığını fark edecek kadar akıllıdır; dolayısıyla bu bir query parametresidir.

## Set tipleri { #set-types }

Sonra bunu düşününce, tag’lerin tekrar etmemesi gerektiğini fark ederiz; büyük ihtimalle benzersiz string’ler olmalıdır.

Python’da benzersiz öğelerden oluşan kümeler için özel bir veri tipi vardır: `set`.

O zaman `tags`’i string’lerden oluşan bir set olarak tanımlayabiliriz:

my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```


/// info | 信息

`**second_user_data` 意思是：

直接将 `second_user_data` 字典的键和值作为 key-value 参数传入，等同于：`User(id=4, name="Mary", joined="2018-11-30")`
