If you call those functions in **other places in your code**, the actual **default values** will be kept, your editor will help you notice missing **required arguments**, Python will require you to pass required arguments at **runtime**, you will be able to **use the same functions** for different things and with different libraries (e.g. **Typer** will soon support `Annotated` too, then you could use the same function for an API and a CLI),...

## `dependencies` zum *Pfadoperation-Dekorator* hinzufügen

Der *Pfadoperation-Dekorator* erhält ein optionales Argument `dependencies`.

Es sollte eine `list`e von `Depends()` sein:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

                throw new IllegalArgumentException("Invalid argument provided");
            }
        };
        ComponentUtil.register(searchEngineClient, "searchEngineClient");

        // Execute the job
        String result = purgeDocJob.execute();

        // Assert error message is in the result
        assertTrue(result.contains("Invalid argument provided"));
    }

## Agregar `dependencies` al decorador de *path operation*

El decorador de *path operation* recibe un argumento opcional `dependencies`.

Debe ser una `list` de `Depends()`:
