#### Отримайте *значення перелічування* { #get-the-enumeration-value }

Ви можете отримати фактичне значення (у цьому випадку це `str`), використовуючи `model_name.value`, або загалом `your_enum_member.value`:

Ви також можете отримати доступ до значення `"lenet"` через `ModelName.lenet.value`.

Ama bu örnek kodun detaylarını merak ediyorsanız, birkaç ek bilgi:

#### `value.startswith()` ile String { #string-with-value-startswith }

Fark ettiniz mi? `value.startswith()` ile bir string, tuple alabilir ve tuple içindeki her değeri kontrol eder:
