Agora, vamos ver o módulo em `app/main.py`.

Aqui é onde você importa e usa a classe `FastAPI`.

Este será o arquivo principal em seu aplicativo que une tudo.

E como a maior parte de sua lógica agora viverá em seu próprio módulo específico, o arquivo principal será bem simples.

### Importar `FastAPI`

Você importa e cria uma classe `FastAPI` normalmente.

Sehen wir uns nun das Modul unter `app/main.py` an.

Hier importieren und verwenden Sie die Klasse `FastAPI`.

Dies ist die Hauptdatei Ihrer Anwendung, die alles zusammen bindet.

Und da sich der Großteil Ihrer Logik jetzt in seinem eigenen spezifischen Modul befindet, wird die Hauptdatei recht einfach sein.

### `FastAPI` importieren

Sie importieren und erstellen wie gewohnt eine `FastAPI`-Klasse.
