Y también puedes definir un valor por defecto `list` de valores si no se proporcionan ninguno:

{* ../../docs_src/query_params_str_validations/tutorial012_an_py39.py hl[9] *}

Si vas a:

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

el valor por defecto de `q` será: `["foo", "bar"]` y tu response será:

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

	}

	var volInfos []VolInfo
	// TestXLStorage empty list vols.
	if volInfos, err = xlStorage.ListVols(t.Context()); err != nil {
		t.Fatalf("expected: <nil>, got: %s", err)
	} else if len(volInfos) != 1 {
		t.Fatalf("expected: one entry, got: %v", volInfos)
	}

	// TestXLStorage non-empty list vols.
	if err = xlStorage.MakeVol(t.Context(), "success-vol"); err != nil {

Por ejemplo, podrías estar trabajando en un proyecto `philosophers-stone`, **activar ese entorno virtual**, instalar paquetes y trabajar con ese entorno.

Y luego quieres trabajar en **otro proyecto** `prisoner-of-azkaban`.

Vas a ese proyecto:

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban
```

</div>
