El parámetro `name` está definido como `Optional[str]`, pero **no es opcional**, no puedes llamar a la función sin el parámetro:

```Python
say_hi()  # ¡Oh, no, esto lanza un error! 😱
```

El parámetro `name` sigue siendo **requerido** (no *opcional*) porque no tiene un valor predeterminado. Aún así, `name` acepta `None` como valor:

```Python

     * @param domainHandle the domain handle containing this alias
     * @param access the desired access rights
     * @param rid the relative identifier of the alias
     * @throws IOException if an I/O error occurs during handle creation
     */
    public SamrAliasHandle(final DcerpcHandle handle, final SamrDomainHandle domainHandle, final int access, final int rid)
            throws IOException {
        this.handle = handle;

If a client tries to send some **extra** data in the **query parameters**, they will receive an **error** response.

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {

        // Test initial state
        assertTrue(response.hasMoreElements());

        // Test after setting error code (not status)
        response.setTestErrorCode(1); // Non-zero errorCode indicates error
        assertFalse(response.hasMoreElements());

        // Reset error and test hasMore flag
        response.setTestErrorCode(0);
        response.hasMore = false;

That way, using `secrets.compare_digest()` in your application code, it will be safe against this whole range of security attacks.

### Return the error { #return-the-error }

  - `kubectl` outputs warnings to stderr, and accepts a `--warnings-as-errors` option to treat warnings as fatal errors
  - `k8s.io/client-go` outputs warnings to stderr by default; override this per-client by setting `config.WarningHandler`, or per-process with `rest.SetDefaultWarningHandler()`
