Como `needy` é um parâmetro obrigatório, você precisaria defini-lo na URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...isso deve funcionar:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

////

Isso significa que:

* A variável `prices` é um dict`:
    * As chaves deste `dict` são do tipo `str` (digamos, o nome de cada item).
    * Os valores deste `dict` são do tipo `float` (digamos, o preço de cada item).

#### Union

Você pode declarar que uma variável pode ser de qualquer um dentre **diversos tipos**. Por exemplo, um `int` ou um `str`.
