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

würden Sie die mehreren `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-`list` in Ihrer *Pfadoperation-Funktion* im *Funktionsparameter* `q` erhalten.

So wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> zu dieser URL:

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

Então, com uma URL como:

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

você receberá os múltiplos valores do *parâmetro de consulta* `q` (`foo` e `bar`) em uma `list` Python dentro da sua *função de operação de rota*, no *parâmetro da função* `q`.

Assim, a resposta para essa URL seria:

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