{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

Der ge`yield`ete Wert ist das, was in *Pfadoperationen* und andere Abhängigkeiten eingefügt wird:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

Der auf die `yield`-Anweisung folgende Code wird ausgeführt, nachdem die Response gesendet wurde:

{* ../../docs_src/dependencies/tutorial007.py hl[5:6] *}

/// tip | Tipp

{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

Полученное значение и есть то, что будет внедрено в функцию операции пути и другие зависимости:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

Код, следующий за оператором `yield`, выполняется после доставки ответа:

{* ../../docs_src/dependencies/tutorial007.py hl[5:6] *}

/// tip | Подсказка

응답을 생성하기 전에는 `yield`문을 포함하여 그 이전의 코드만이 실행됩니다:

{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

yield된 값은 *경로 작업* 및 다른 의존성들에 주입되는 값 입니다:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

`yield`문 다음의 코드는 응답을 생성한 후 보내기 전에 실행됩니다:

{* ../../docs_src/dependencies/tutorial007.py hl[5:6] *}

/// tip | 팁

`async` 함수와 일반 함수 모두 사용할 수 있습니다.

# Classes as Dependencies { #classes-as-dependencies }

Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example { #a-dict-from-the-previous-example }

In the previous example, we were returning a `dict` from our dependency ("dependable"):

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Observe o método `__init__` usado para criar uma instância da classe:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...ele possui os mesmos parâmetros que nosso `common_parameters` anterior:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8] *}

{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

El valor generado es lo que se inyecta en *path operations* y otras dependencias:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

El código posterior a la declaración `yield` se ejecuta después de crear el response pero antes de enviarla:

{* ../../docs_src/dependencies/tutorial007.py hl[5:6] *}
