Затем с `random.choice()` можно получить **случайное значение** из списка — то есть кортеж вида `(id, name)`. Это будет что‑то вроде `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

После этого мы **присваиваем эти два значения** кортежа переменным `id` и `name`.

Так что, если пользователь не передал ID элемента, он всё равно получит случайную рекомендацию.

/// tip | Consejo

Eres libre de usar cada operación (método HTTP) como quieras.

**FastAPI** no fuerza ningún significado específico.

La información aquí se presenta como una guía, no un requisito.

Por ejemplo, cuando usas GraphQL normalmente realizas todas las acciones usando solo operaciones `POST`.

///

Dependências com `yield` evoluíram ao longo do tempo para cobrir diferentes casos de uso e corrigir alguns problemas.

Se você quiser ver o que mudou em diferentes versões do FastAPI, você pode ler mais sobre isso no guia avançado, em [Dependências Avançadas - Dependências com `yield`, `HTTPException`, `except` e Tarefas de Background](../../advanced/advanced-dependencies.md#dependencies-with-yield-httpexception-except-and-background-tasks).

Estes detalhes são específicos da implementação.

Para o OAuth2, eles são apenas strings.

## Visão global { #global-view }

Primeiro, vamos olhar rapidamente as partes que mudam dos exemplos do **Tutorial - Guia de Usuário** para [OAuth2 com Senha (e hash), Bearer com tokens JWT](../../tutorial/security/oauth2-jwt.md). Agora utilizando escopos OAuth2:

    * JSON 객체 (`dict`).
    * 아이템 타입을 정의하는 JSON 배열 (`list`).
    * 최소/최대 길이를 정의하는 문자열(`str`) 필드.
    * 최소/최대 값을 가지는 숫자(`int`, `float`) 등.

* 다음과 같은 좀 더 이색적인 타입에 대한 검증:
    * URL.
    * Email.
    * UUID.
    * ...그 외.

모든 검증은 잘 확립되어 있고 견고한 **Pydantic**이 처리합니다.
