Und wenn Sie diesen lokalen FastAPI-Quellcode aktualisieren und dann die Python-Datei erneut ausführen, wird die neue Version von FastAPI verwendet, die Sie gerade bearbeitet haben.

Auf diese Weise müssen Sie Ihre lokale Version nicht „installieren“, um jede Änderung testen zu können.

Dies ist ein mehr oder weniger fortgeschrittener Abschnitt. Wenn Sie gerade erst anfangen, können Sie ihn überspringen.

Sie benötigen nicht unbedingt OAuth2-Scopes, und Sie können die Authentifizierung und Autorisierung handhaben wie Sie möchten.

### Reiniciar após falha

Mas nos casos com erros realmente graves que travam o **processo** em execução, você vai querer um componente externo que seja responsável por **reiniciar** o processo, pelo menos algumas vezes...

### Include an `APIRouter` with a custom `prefix`, `tags`, `responses`, and `dependencies`

Now, let's imagine your organization gave you the `app/internal/admin.py` file.

It contains an `APIRouter` with some admin *path operations* that your organization shares between several projects.

That's what would happen to a third party application that tried to access one of these *path operations* with a token provided by a user, depending on how many permissions the user gave the application.

## About third party integrations

In this example we are using the OAuth2 "password" flow.

This is appropriate when we are logging in to our own application, probably with our own frontend.
