## URL-адреси документації

Ви можете налаштувати два інтерфейси користувача для документації, які включені:

* **Swagger UI**: доступний за адресою `/docs`.
    * Ви можете змінити його URL за допомогою параметра `docs_url`.
    * Ви можете вимкнути його, встановивши `docs_url=None`.
* **ReDoc**: доступний за адресою `/redoc`.

## Optional parameters { #optional-parameters }

The same way, you can declare optional query parameters, by setting their default to `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

In this case, the function parameter `q` will be optional, and will be `None` by default.

/// check

     *
     * @param namePrefix the prefix that JAR file names should start with
     * @return an array of File objects representing matching JAR files, or empty array if none found
     */
    public static File[] getJarFiles(final String namePrefix) {
        final ServletContext context = LaServletContextUtil.getServletContext();
        if (context == null) {
            return new File[0];

        } catch (final UnsupportedEncodingException e) {
            throw new UnsupportedEncodingRuntimeException(e);
        }
    }

    /**
     * Polls an encryption cipher from the queue, creating a new one if none are available.
     *
     * @return an encryption cipher
     */
    protected Cipher pollEncryptoCipher() {
        Cipher cipher = encryptoQueue.poll();
        if (cipher == null) {

`Optional[Something]` насправді є скороченням для `Union[Something, None]`, вони еквівалентні.

Це також означає, що в Python 3.10 ви можете використовувати `Something | None`:

//// tab | Python 3.8 і вище

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial009.py!}
```

## Docs URLs { #docs-urls }

You can configure the two documentation user interfaces included:

* **Swagger UI**: served at `/docs`.
    * You can set its URL with the parameter `docs_url`.
    * You can disable it by setting `docs_url=None`.
* **ReDoc**: served at `/redoc`.
