Мы можем создать экземпляр этого класса так:

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

Так мы «параметризуем» нашу зависимость: теперь внутри неё хранится "bar" в атрибуте `checker.fixed_content`.

## Используем экземпляр как зависимость { #use-the-instance-as-a-dependency }

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

Und auf diese Weise können wir unsere Abhängigkeit „parametrisieren“, die jetzt `"bar"` enthält, als das Attribut `checker.fixed_content`.

## Die Instanz als Abhängigkeit verwenden { #use-the-instance-as-a-dependency }

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

E deste modo nós podemos "parametrizar" a nossa dependência, que agora possui `"bar"` dentro dele, como o atributo `checker.fixed_content`.

## Utilize a instância como dependência { #use-the-instance-as-a-dependency }

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

And that way we are able to "parameterize" our dependency, that now has `"bar"` inside of it, as the attribute `checker.fixed_content`.

## Use the instance as a dependency { #use-the-instance-as-a-dependency }

{* ../../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 }
