```console
$ pip install fastapi

Bạn cũng sẽ cần một ASGI server cho production như <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> hoặc <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.

 * those tasks.
 *
 * <p>Submitted tasks have a happens-before order as defined in the Java Language Specification.
 * Tasks execute with the same happens-before order that the function calls to {@link #submit} and
 * {@link #submitAsync} that submitted those tasks had.
 *
 * <p>This class has limited support for cancellation and other "early completions":

 * <ul>

また、値が指定されていない場合はデフォルトの`list`を定義することもできます。

{* ../../docs_src/query_params_str_validations/tutorial012.py hl[9] *}

以下のURLを開くと:

```
http://localhost:8000/items/
```

`q`のデフォルトは: `["foo", "bar"]` となり、レスポンスは以下のようになります:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

#### `list`を使う

`List[str]`の代わりに直接`list`を使うこともできます:

También vuelve a declarar `id: int`. Al hacer esto, estamos haciendo un **contrato** con los clientes de la API, para que siempre puedan esperar que el `id` esté allí y sea un `int` (nunca será `None`).
