## Ön Tanımlı Değerler

Eğer *yol parametresi* alan bir *yol operasyonunuz* varsa ve alabileceği *yol parametresi* değerlerinin ön tanımlı olmasını istiyorsanız, standart Python <abbr title="Enumeration">`Enum`</abbr> tipini kullanabilirsiniz.

### Bir `Enum` Sınıfı Oluşturalım

`Enum` sınıfını projemize dahil edip `str` ile `Enum` sınıflarını miras alan bir alt sınıf yaratalım.
