# Ambientes Virtuais

Ao trabalhar em projetos Python, você provavelmente deve usar um **ambiente virtual** (ou um mecanismo similar) para isolar os pacotes que você instala para cada projeto.

/// info | Informação

Se você já sabe sobre ambientes virtuais, como criá-los e usá-los, talvez seja melhor pular esta seção. 🤓

/// tip | Dica

Um **ambiente virtual** é diferente de uma **variável de ambiente**.

                return null;
            }
            final String requestsPerSecond = String.valueOf(fessConfig.getIndexReindexSizeAsInteger() * fessConfig.availableProcessors());
            logger.info("Set requests_per_second to {}", requestsPerSecond);
            return requestsPerSecond;
        }
        return value;
    }

    /**
     * Creates a new index with default settings.
     *

        return UUID.randomUUID().toString().replace("-", StringUtil.EMPTY);
    }

    /**
     * Updates the user session with the provided user code.
     * This method registers the user info with the search log helper and updates the cookie.
     *
     * @param userCode the user code to associate with the session
     */
    protected void updateUserSessionId(final String userCode) {

            log.debug("Secure negotiation failure");
            throw new CIFSException("Mismatched attributes validating negotiate info");
        }

        log.debug("Secure negotiation OK");
    }

    /**
     * @param transport
     * @return
     * @throws SmbException
     */

* The translation doesn't use different Markdown structures, for example adding HTML tags when the original didn't have them.
* The "admonition" sections, like `tip`, `info`, etc. are not changed or translated. For example:

```
/// tip

This is a tip.

///

```

looks like this:

/// tip

This is a tip.

///

    }

    /**
     * Updates highlight information based on screen width.
     * Reduces fragment size for smaller screens.
     *
     * @param highlightInfo the highlight info to update
     * @param width the screen width
     */
    protected void updateHighlightInfo(final HighlightInfo highlightInfo, final int width) {
        if (width < TABLET_WIDTH) {

     *
     * @param body search parameters for filtering and pagination
     * @return JSON response containing elevate word settings list with pagination info
     */
    @Execute
    public JsonResponse<ApiResult> settings(final SearchBody body) {
        validateApi(body, messages -> {});
        final ElevateWordPager pager = copyBeanToNewBean(body, ElevateWordPager.class);

Sonrasında, sınıf içerisinde, mevcut ve geçerli değerler olacak olan sabit değerli özelliklerini oluşturalım:

{* ../../docs_src/path_params/tutorial005.py hl[1,6:9] *}

/// info | Bilgi

3.4 sürümünden beri <a href="https://docs.python.org/3/library/enum.html" class="external-link" target="_blank">enumerationlar (ya da enumlar) Python'da mevcuttur</a>.

///

/// tip | İpucu

Після цього створіть атрибути класу з фіксованими значеннями, які будуть доступними допустимими значеннями:

{* ../../docs_src/path_params/tutorial005.py hl[1,6:9] *}

/// info | Додаткова інформація

<a href="https://docs.python.org/3/library/enum.html" class="external-link" target="_blank">Перелічення (або enums) доступні в Python</a> починаючи з версії 3.4.

///

/// tip | Порада

デフォルトでは、単数値はクエリパラメータとして解釈されるので、明示的に `Query` を追加する必要はありません。

```Python
q: str = None
```

以下において:

{* ../../docs_src/body_multiple_params/tutorial004.py hl[27] *}

/// info | 情報

`Body`もまた、後述する `Query` や `Path` などと同様に、すべての検証パラメータとメタデータパラメータを持っています。

///

## 単一のボディパラメータの埋め込み

Pydanticモデル`Item`のボディパラメータ`item`を1つだけ持っているとしましょう。

デフォルトでは、**FastAPI**はそのボディを直接期待します。
