例如，`dependency_c` 可以依赖于 `dependency_b`，而 `dependency_b` 则依赖于 `dependency_a`。

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

所有这些依赖都可以使用 `yield`。

在这种情况下，`dependency_c` 在执行其退出代码时需要 `dependency_b`（此处称为 `dep_b`）的值仍然可用。

而 `dependency_b` 反过来则需要 `dependency_a`（此处称为 `dep_a` ）的值在其退出代码中可用。

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[18:19,26:27] *}

同样，你可以混合使用带有 `yield` 或 `return` 的依赖。

你也可以声明一个依赖于多个带有 `yield` 的依赖，等等。

Pero está ahí para ti si la necesitas. 🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Но если понадобится — возможность есть. 🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Aber es ist für Sie da, wenn Sie es brauchen. 🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Mas ela existe para ser utilizada caso você precise. 🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

But it's there for you if you need it. 🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

If you want to catch exceptions and create a custom response based on that, create a [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

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

이들 모두는 `yield`를 사용할 수 있습니다.

이 경우 `dependency_c`는 종료 코드를 실행하기 위해, `dependency_b`의 값 (여기서는 `dep_b`로 명명)이 여전히 사용 가능해야 합니다.

그리고, `dependency_b`는 종료 코드를 위해 `dependency_a`의 값 (여기서는 `dep_a`로 명명) 이 사용 가능해야 합니다.
