Then, with a URL like:

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

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

So, the response to that URL would be:

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