¿Quieres solo tener un `str`? ¿O solo un `dict`? ¿O un instance de clase modelo de base de datos directamente? Todo funciona de la misma manera.

¿En realidad no tienes usuarios que inicien sesión en tu aplicación sino robots, bots u otros sistemas, que solo tienen un token de acceso? Una vez más, todo funciona igual.

Remember how our app/file structure looks like:

The two dots `..`, like in:

```Python
from ..dependencies import get_token_header
```

mean:

* Starting in the same package that this module (the file `app/routers/items.py`) lives in (the directory `app/routers/`)...

    /*
     * TODO: cpovirk - Pre-size the HashMap based on the number of enum values? (But *not* based on
     * the number of entries in the map, as that makes it easy for hostile inputs to trigger lots of
     * allocation—not that any program should be deserializing hostile inputs to begin with!)
