## Wie es aussieht { #how-it-looks }

Lassen Sie uns zunächst einfach den Code verwenden und sehen, wie er funktioniert, und dann kommen wir zurück, um zu verstehen, was passiert.

## `main.py` erstellen { #create-main-py }

Kopieren Sie das Beispiel in eine Datei `main.py`:

### Crie uma classe `Enum` { #create-an-enum-class }

Importe `Enum` e crie uma subclasse que herde de `str` e de `Enum`.

Ao herdar de `str`, a documentação da API saberá que os valores devem ser do tipo `string` e poderá renderizá-los corretamente.

	if logCh != nil {
		// We are not allowed to add when logCh is nil
		h.wg.Add(1)
		defer h.wg.Done()

	if logCh == nil {
		return

	// from an internal channel.

В Pydantic v1 он входил в основной пакет. Теперь он распространяется как отдельный пакет, чтобы вы могли установить его только при необходимости.

### Создание объекта `Settings` { #create-the-settings-object }

Импортируйте `BaseSettings` из Pydantic и создайте подкласс, очень похожий на Pydantic‑модель.
