Например, `dependency_c` может зависеть от `dependency_b`, а `dependency_b` — от `dependency_a`:

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[6,14,22] *}

И все они могут использовать `yield`.

В этом случае `dependency_c` для выполнения своего кода выхода нуждается в том, чтобы значение из `dependency_b` (здесь `dep_b`) всё ещё было доступно.
