## Crear una instance { #create-an-instance }

Podríamos crear una instance de esta clase con:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

Y de esa manera podemos "parametrizar" nuestra dependencia, que ahora tiene `"bar"` dentro de ella, como el atributo `checker.fixed_content`.

## Usar la instance como una dependencia { #use-the-instance-as-a-dependency }

Lorsque vous importez `Query`, `Path` et d'autres de `fastapi`, ce sont en fait des fonctions.

Ces dernières, lorsqu'elles sont appelées, renvoient des instances de classes du même nom.

Ainsi, vous importez `Query`, qui est une fonction. Et lorsque vous l'appelez, elle renvoie une instance d'une classe également nommée `Query`.
