We had this type annotation:

//// tab | Python 3.10+

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

////

//// tab | Python 3.9+

```Python
q: Union[str, None] = None
```

////

What we will do is wrap that with `Annotated`, so it becomes:

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

////

//// tab | Python 3.9+

```Python

## Múltiples Workers { #multiple-workers }

Puedes iniciar múltiples workers con la opción de línea de comando `--workers`:

//// tab | `fastapi`

Si usas el comando `fastapi`:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

- Click `Create subproject` button at the bottom of the "Subprojects" region of [this page](https://builds.gradle.org/admin/editProject.html?projectId=Gradle&tab=projectGeneralTab)
  - Select `Manually`.
  - Give it a name. The name will be displayed on TeamCity web UI. We highly recommend it be capitalized from the branch name, i.e. `MyTestBranch`.

			prefix:         "testdir/",
			expectedNonRec: false,
			expectedRec:    true,
		},
		// case 5 - has filter with prefix and tags, here we are not matching on tags

	commandsTree := trie.NewTrie()

	// registerCommand registers a cli command.
	registerCommand := func(command cli.Command) {
		// avoid registering commands which are not being built (via

		commands = append(commands, command)
		commandsTree.Insert(command.Name)
	}

	findClosestCommands := func(command string) []string {

	remote := m.targets[cReq.Host]
	if remote == nil {
		writeErr(fmt.Errorf("unknown incoming host: %v", cReq.Host))

	}
	if time.Since(cReq.Time).Abs() > 5*time.Minute {
		writeErr(fmt.Errorf("time difference too large between servers: %v", time.Since(cReq.Time).Abs()))

/// note | 技術詳細

また、`from starlette import status`を使用することもできます。

**FastAPI** は開発者の利便性を考慮して、`fastapi.status`と同じ`starlette.status`を提供しています。しかし、これはStarletteから直接提供されています。

## タグ

`tags`パラメータを`str`の`list`（通常は１つの`str`）と一緒に渡すと、*path operation*にタグを追加できます:

{* ../../docs_src/path_operation_configuration/tutorial002.py hl[17,22,27] *}

これらはOpenAPIスキーマに追加され、自動ドキュメントのインターフェースで使用されます:

    ],
    extra_copts = if_pywrap(["-DTENSORFLOW_NO_SHARED_OBJECTS"]),
    linkopts = select({
        "//tensorflow:macos": ["-headerpad_max_install_names"],
        "//conditions:default": [],
    }),
    tags = [
        "no_cuda_asan",  # TODO(b/181771536)
        "no_windows",  # TODO(b/155444728)
    ],
    # We must ensure that the dependencies can be dynamically linked since
