### 3.2 Directory Cache Scopes
```java
public enum DirectoryCacheScope {
    IMMEDIATE_CHILDREN,    // Only direct children
    RECURSIVE_TREE,        // Entire subtree (if supported)

* and in there, find the module `dependencies` (the file at `app/dependencies.py`)...
* and from it, import the function `get_token_header`.

That works correctly! 🎉

The same way, if we had used three dots `...`, like in:

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

that would mean:

   * then the effect of the function is non-existent: we serve storedPermits at exactly the same
   * cost as fresh ones (1/QPS is the cost for each). We use this trick later.
   *
   * If we pick a function that goes /below/ that horizontal line, it means that we reduce the area
   * of the function, thus time. Thus, the RateLimiter becomes /faster/ after a period of

      /*
       * The following static final fields exist for performance reasons.
       *
       * In UnsignedBytesBenchmark, accessing the following objects via static final fields is the
       * fastest (more than twice as fast as the Java implementation, vs ~1.5x with non-final static
       * fields, on x86_32) under the Hotspot server compiler. The reason is obviously that the
       * non-final fields need to be reloaded inside the loop.

                }
            }

            context.logger.error("");

            if (!context.options().showErrors().orElse(false)) {
                context.logger.error("To see the full stack trace of the errors, re-run Maven with the '"
                        + MessageUtils.builder().strong("-e") + "' switch");
            }
            if (!context.invokerRequest.effectiveVerbose()) {

And in the code, we get a `dict` with all the data sent by the client, **only the data sent by the client**, excluding any values that would be there just for being the default values. To do it we use `exclude_unset=True`. This is the main trick. 🪄

Then we use `hero_db.sqlmodel_update(hero_data)` to update the `hero_db` with the data from `hero_data`.

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[83:93] hl[83:84,88:89] *}

Convertimos este objeto iterable en una `list` propiamente dicha con `list(data.items())`.

Luego con `random.choice()` podemos obtener un valor aleatorio de la lista, así que obtenemos una tupla con `(id, name)`. Será algo como `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.
