因此，在我们的示例中，我们可以将 `tags` 明确地指定为一个「字符串列表」：

//// tab | Python 3.10+

```Python hl_lines="12"
{!> ../../docs_src/body_nested_models/tutorial002_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="14"
{!> ../../docs_src/body_nested_models/tutorial002_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="14"
{!> ../../docs_src/body_nested_models/tutorial002.py!}
```

You can set them as follows:

```Python hl_lines="3-16  19-32"
{!../../docs_src/metadata/tutorial001.py!}
```

You can write Markdown in the `description` field and it will be rendered in the output.
