## Type Hints met Metadata Annotaties

Python heeft ook een functie waarmee je **extra <abbr title="Data over de data, in dit geval informatie over het type, bijvoorbeeld een beschrijving.">metadata</abbr>** in deze type hints kunt toevoegen met behulp van `Annotated`.

//// tab | Python 3.9+

In Python 3.9 is `Annotated` onderdeel van de standaardpakket, dus je kunt het importeren vanuit `typing`.

This simple case is handled automatically by FastAPI because the return type annotation is the class (or a subclass of) `Response`.

And tools will also be happy because both `RedirectResponse` and `JSONResponse` are subclasses of `Response`, so the type annotation is correct.

### Annotate a Response Subclass

You can also use a subclass of `Response` in the type annotation:

```Python hl_lines="8-9"

      if (annotations == null) {
        annotations = new ArrayList<>();
        for (Annotation a : classOrMethod.getDeclaredAnnotations()) {
          if (a.annotationType().isAnnotationPresent(TesterAnnotation.class)) {
            annotations.add(a);
          }
        }
        annotations = unmodifiableList(annotations);
        annotationCache.put(classOrMethod, annotations);
      }
      return annotations;
    }
  }
