You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.

Zum Beispiel könnten Sie eine Datei `main.py` haben mit:

```Python hl_lines="3"
import os

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

/// tip | Tipp

Das zweite Argument von [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) ist der Defaultwert, der zurückgegeben wird.

/// tip | Tipp

Der Query-Parameter `callback_url` verwendet einen Pydantic-[Url](https://docs.pydantic.dev/latest/api/networks/)-Typ.

///

Das einzig Neue ist `callbacks=invoices_callback_router.routes` als Argument für den *Pfadoperation-Dekorator*. Wir werden als Nächstes sehen, was das ist.

## Dokumentation des Callbacks { #documenting-the-callback }

Der tatsächliche Callback-Code hängt stark von Ihrer eigenen API-Anwendung ab.

```Python hl_lines="3"
import os

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

/// tip | Astuce

Le deuxième argument de [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) est la valeur par défaut à retourner.

S'il n'est pas fourni, c'est `None` par défaut ; ici, nous fournissons `"World"` comme valeur par défaut à utiliser.
