The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

Vous pouvez obtenir la valeur réel d'un membre (une chaîne de caractères ici), avec `model_name.value`, ou en général, `votre_membre_d'enum.value` :

{* ../../docs_src/path_params/tutorial005.py hl[20] *}

/// tip | Astuce

Vous pouvez aussi accéder la valeur `"lenet"` avec `ModelName.lenet.value`.

  They are replaced in Maven 4 with Maven 4 API Core's {{{../../api/maven-api-core/apidocs/org/apache/maven/api/Type.html}Dependency Types}},
  with default values defined in {{{../../compat/maven-resolver-provider/apidocs/org/apache/maven/repository/internal/type/DefaultTypeProvider.html}DefaultTypeProvider}}.

  For compatibility, legacy Maven 3 artifact handlers are still provided:

async def get_model(model_name: ModelName):
    if model_name is ModelName.alexnet:
        return {"model_name": model_name, "message": "Deep Learning FTW!"}

    if model_name.value == "lenet":
        return {"model_name": model_name, "message": "LeCNN all the images"}
