## `Annotated` как тип для query-параметра `q`

Помните, как ранее я говорил об Annotated? Он может быть использован для добавления метаданных для ваших параметров в разделе [Введение в аннотации типов Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Пришло время использовать их в FastAPI. 🚀

У нас была аннотация следующего типа:

//// tab | Python 3.10+

```Python
q: str | None = None
```

FastAPI is een modern, snel (zeer goede prestaties), web framework voor het bouwen van API's in Python, gebruikmakend van standaard Python type-hints.

De belangrijkste kenmerken zijn:

* **Snel**: Zeer goede prestaties, vergelijkbaar met **NodeJS** en **Go** (dankzij Starlette en Pydantic). [Een van de snelste beschikbare Python frameworks](#prestaties).

				if len(pl.Items) < 1 {
					return errors.New("no pods found")

					log.Warnf("more than 1 pods fits selector: %s; will use pod: %s", labelSelector, pl.Items[0].Name)
				}

				// only use the first pod in the list
				podName = pl.Items[0].Name
				ns = pl.Items[0].Namespace

 * <i>if and only if</i> {@code a.equals(b)}. If this advice is not followed, the resulting
 * collection will not correctly obey its specification.
