*Декоратор операции пути* получает необязательный аргумент `dependencies`.

Это должен быть `list` состоящий из `Depends()`:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

Зависимости из dependencies выполнятся так же, как и обычные зависимости. Но их значения (если они были) не будут переданы в *функцию операции пути*.

You can define dependencies that in turn can define dependencies themselves.

In the end, a hierarchical tree of dependencies is built, and the **Dependency Injection** system takes care of solving all these dependencies for you (and their sub-dependencies) and providing (injecting) the results at each step.

* All these *path operations* will have the list of `dependencies` evaluated/executed before them.
    * If you also declare dependencies in a specific *path operation*, **they will be executed too**.
    * The router dependencies are executed first, then the [`dependencies` in the decorator](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, and then the normal parameter dependencies.
