Aquí hay un ejemplo más completo.

Usa una dependencia para comprobar si el nombre de usuario y la contraseña son correctos.

Para esto, usa el módulo estándar de Python <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> para verificar el nombre de usuario y la contraseña.

Hier ist ein vollständigeres Beispiel.

Verwenden Sie eine Abhängigkeit, um zu überprüfen, ob Benutzername und Passwort korrekt sind.

Verwenden Sie dazu das Python-Standardmodul <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a>, um den Benutzernamen und das Passwort zu überprüfen.

/// tip

Here we use <a href="https://docs.python.org/3/library/time.html#time.perf_counter" class="external-link" target="_blank">`time.perf_counter()`</a> instead of `time.time()` because it can be more precise for these use cases. 🤓

## Technical Details { #technical-details }

Just a technical detail for the curious nerds. 🤓

Underneath, in the ASGI technical specification, this is part of the <a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">Lifespan Protocol</a>, and it defines events called `startup` and `shutdown`.

/// info

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.

If not provided, it's `None` by default, here we provide `"World"` as the default value to use.
