Pero ahora sabes cómo funciona, para que puedas usar imports relativos en tus propias aplicaciones sin importar cuán complejas sean. 🤓

### Agregar algunos `tags`, `responses`, y `dependencies` personalizados

No estamos agregando el prefijo `/items` ni los `tags=["items"]` a cada *path operation* porque los hemos añadido al `APIRouter`.

This was designed this way mainly to allow using the same objects "yielded" by dependencies inside of background tasks, because the exit code would be executed after the background tasks were finished.

Nevertheless, as this would mean waiting for the response to travel through the network while unnecessarily holding a resource in a dependency with yield (for example a database connection), this was changed in FastAPI 0.106.0.

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

//// tab | Python 3.8+

```Python
q: Annotated[Union[str, None]] = None
```

Both of those versions mean the same thing, `q` is a parameter that can be a `str` or `None`, and by default, it is `None`.

Now let's jump to the fun stuff. 🎉
