Bu, alanın **her zaman bir değeri olacağı** anlamına gelir; sadece bazen bu değer `None` olabilir (JSON'da `null`).

Dolayısıyla API'nizi kullanan client'ların bu değerin var olup olmadığını kontrol etmesine gerek yoktur; **alanın her zaman mevcut olacağını varsayabilirler**, sadece bazı durumlarda default değer olan `None` gelecektir.
