Vamos imaginar que queremos ter uma dependência que verifica se o parâmetro de consulta `q` possui um valor fixo.

Porém nós queremos poder parametrizar o conteúdo fixo.

## Uma instância "chamável"

Em Python existe uma maneira de fazer com que uma instância de uma classe seja um "chamável".

Não propriamente a classe (que já é um chamável), mas a instância desta classe.

Para fazer isso, nós declaramos o método `__call__`:

        assert response.status_code == 404, response.text

        # Delete a hero that does not exist
        response = client.delete(f"/heroes/{hero_id}")
        assert response.status_code == 404, response.text
        assert response.json() == snapshot({"detail": "Hero not found"})

        # Update a hero that does not exist
        response = client.patch(f"/heroes/{hero_id}", json={"name": "Dog Pond"})

### Types génériques avec des paramètres de types

Il existe certaines structures de données qui contiennent d'autres valeurs, comme `dict`, `list`, `set` et `tuple`. Et les valeurs internes peuvent elles aussi avoir leurs propres types.

Pour déclarer ces types et les types internes, on utilise le module standard de Python `typing`.

Il existe spécialement pour supporter ces annotations de types.

#### `List`

  GENERAL_PURPOSE(
      CollectionFeature.GENERAL_PURPOSE,
      SUPPORTS_SET,
      SUPPORTS_ADD_WITH_INDEX,
      SUPPORTS_REMOVE_WITH_INDEX),

  /** Features supported by lists where only removal is allowed. */
  REMOVE_OPERATIONS(CollectionFeature.REMOVE_OPERATIONS, SUPPORTS_REMOVE_WITH_INDEX);

  private final Set<Feature<? super List>> implied;

  ListFeature(Feature<? super List>... implied) {

	return e.Bucket + " invalid bucket name error: " + e.Err.Error()
}

func (e Error) Error() string {
	return "dns related error: " + e.Err.Error()
}

// ErrBucketConflict for buckets that already exist
type ErrBucketConflict Error

func (e ErrBucketConflict) Error() string {
	return e.Bucket + " bucket conflict error: " + e.Err.Error()
}

// Store dns record store
type Store interface {
