Obwohl wir nicht die standardmäßig integrierte Funktionalität verwenden, verwenden wir dennoch ein Pydantic-Modell, um das JSON-Schema für die Daten, die wir in YAML empfangen möchten, manuell zu generieren.

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

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

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

El código posterior a la declaración `yield` se ejecuta después del response:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}

O valor gerado (yielded) é o que é injetado nas *operações de rota* e outras dependências:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

O código após o `yield` é executado após a resposta:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}

/// tip | Dica

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

The yielded value is what is injected into *path operations* and other dependencies:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

The code following the `yield` statement is executed after the response:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}

/// tip

You can use `async` or regular functions.

Так как редактор кода знает типы переменных, вы получаете не только автозавершение, но и проверки ошибок:

Теперь вы знаете, что нужно исправить — преобразовать `age` в строку с помощью `str(age)`:

{* ../../docs_src/python_types/tutorial004_py39.py hl[2] *}
