```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

但如果你改為造訪：

```
http://127.0.0.1:8000/items/?skip=20
```

函式中的參數值會是：

* `skip=20`：因為你在 URL 中設定了它
* `limit=10`：因為那是預設值

## 選用參數 { #optional-parameters }

同樣地，你可以將預設值設為 `None` 來宣告選用的查詢參數：

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

在這種情況下，函式參數 `q` 為選用，且預設為 `None`。

하지만 가령 아래로 이동한 경우:

```
http://127.0.0.1:8000/items/?skip=20
```

함수의 매개변수 값은 아래가 됩니다:

* `skip=20`: URL에서 지정했기 때문입니다
* `limit=10`: 기본값이기 때문입니다

## 선택적 매개변수 { #optional-parameters }

같은 방법으로 기본값을 `None`으로 설정하여 선택적 매개변수를 선언할 수 있습니다:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

이 경우 함수 매개변수 `q`는 선택적이며 기본값으로 `None` 값이 됩니다.
