  1. docs/de/docs/advanced/events.md

    Dies kann sehr nützlich sein, um **Ressourcen** einzurichten, die Sie in der gesamten Anwendung verwenden wollen und die von Requests **gemeinsam genutzt** werden und/oder die Sie anschließend **aufräumen** müssen. Zum Beispiel ein Pool von Datenbankverbindungen oder das Laden eines gemeinsam genutzten Modells für maschinelles Lernen.
    
    ## Anwendungsfall

  2. docs/pt/docs/advanced/events.md

    Pode ser muito útil para configurar **recursos** que você precisa usar por toda aplicação, e que são **compartilhados** entre as requisições, e/ou que você precisa **limpar** depois. Por exemplo, o pool de uma conexão com o banco de dados ou carregamento de um modelo compartilhado de aprendizado de máquina (_machine learning_).
    
    ## Caso de uso
    
    Vamos iniciar com um exemplo de **caso de uso** e então ver como resolvê-lo com isso.

  3. docs/ru/docs/python-types.md

    # Введение в аннотации типов Python
    
    Python имеет поддержку необязательных аннотаций типов.
    
    **Аннотации типов** являются специальным синтаксисом, который позволяет определять <abbr title="например: str, int, float, bool">тип</abbr> переменной.
    
    Объявление типов для переменных позволяет улучшить поддержку вашего кода редакторами и различными инструментами.

  4. docs/uk/docs/python-types.md

    Python підтримує додаткові "підказки типу" ("type hints") (також звані "анотаціями типу" ("type annotations")).
    
    Ці **"type hints"** є спеціальним синтаксисом, що дозволяє оголошувати <abbr title="наприклад: str, int, float, bool">тип</abbr> змінної.
    
    За допомогою оголошення типів для ваших змінних, редактори та інструменти можуть надати вам кращу підтримку.

  9. docs/en/docs/tutorial/path-params.md

    You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.
    
    Several of these are explored in the next chapters of the tutorial.
    
    ## Order matters
    
    When creating *path operations*, you can find situations where you have a fixed path.

  10. docs/ko/docs/tutorial/body.md

        ```Python hl_lines="18"
        {!> ../../../docs_src/body/tutorial004.py!}
        ```
    
    함수 매개변수는 다음을 따라서 인지하게 됩니다:
    
    * 만약 매개변수가 **경로**에도 선언되어 있다면, 이는 경로 매개변수로 사용될 것입니다.
    * 만약 매개변수가 (`int`, `float`, `str`, `bool` 등과 같은) **유일한 타입**으로 되어있으면, **쿼리** 매개변수로 해석될 것입니다.
    * 만약 매개변수가 **Pydantic 모델** 타입으로 선언되어 있으면, 요청 **본문**으로 해석될 것입니다.
    
    !!! note "참고"
        FastAPI는 `q`의 값이 필요없음을 알게 될 것입니다. 기본 값이 `= None`이기 때문입니다.
