### Tags com Enums

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:

{* ../../docs_src/path_operation_configuration/tutorial002b.py hl[1,8:10,13,18] *}

{* ../../docs_src/sub_applications/tutorial001.py hl[11,14:16] *}

### Monte a sub-aplicação

Na sua aplicação de nível superior, `app`, monte a sub-aplicação, `subapi`.

Neste caso, ela será montada no caminho `/subapi`:

{* ../../docs_src/sub_applications/tutorial001.py hl[11,19] *}

### Verifique a documentação automática da API

### `Union` no Python 3.10

Neste exemplo, passamos `Union[PlaneItem, CarItem]` como o valor do argumento `response_model`.
