Entonces, con una URL como:

```
http://localhost:8000/items/?q=foo&q=bar
```

recibirías los múltiples valores del *query parameter* `q` (`foo` y `bar`) en una `list` de Python dentro de tu *path operation function*, en el *parámetro de función* `q`.

Entonces, el response a esa URL sería:

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