你可以在「路徑操作裝飾器」上設定 `response_model_exclude_unset=True`：

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

如此這些預設值就不會被包含在回應中，只有實際被設定的值才會包含。

因此，如果你對該「路徑操作」發送針對 ID 為 `foo` 的項目的請求，回應（不包含預設值）會是：

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

/// info | 說明

你也可以使用：

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

     * the other. From the declaration syntax, the class type parameter appears first, but the call
     * syntax may show up in opposite order such as {@code new <A>Foo<B>()}.

    public final TypeVariable<?>[] getTypeParameters() {
      TypeVariable<?>[] declaredByClass = getDeclaringClass().getTypeParameters();

そのため、`something`オブジェクト（関数ではないかもしれませんが）を持っていて、それを次のように「呼び出す」（実行する）ことができるとします:

```Python
something()
```

または

```Python
something(some_argument, some_keyword_argument="foo")
```

これを「呼び出し可能」なものと呼びます。

## 依存関係としてのクラス { #classes-as-dependencies_1 }

Pythonのクラスのインスタンスを作成する際に、同じ構文を使用していることに気づくかもしれません。

例えば:

```Python
class Cat:
    def __init__(self, name: str):

  }

  public void testRemoveFromStringHeap() {
    MinMaxPriorityQueue<String> mmHeap =
        rawtypeToWildcard(MinMaxPriorityQueue.expectedSize(5)).create();
    Collections.addAll(mmHeap, "foo", "bar", "foobar", "barfoo", "larry", "sergey", "eric");
    assertTrue("Heap is not intact initially", mmHeap.isIntact());
    assertThat(mmHeap.peek()).isEqualTo("bar");
    assertThat(mmHeap.peekLast()).isEqualTo("sergey");
