* `tax: float = 10.5` has a default of `10.5`.
* `tags: List[str] = []` has a default of an empty list: `[]`.

but you might want to omit them from the result if they were not actually stored.

For example, if you have models with many optional attributes in a NoSQL database, but you don't want to send very long JSON responses full of default values.

## パラメータとして宣言 { #declare-it-as-a-parameter }

*path operation* に追加するには、パスパラメータやクエリパラメータを宣言したのと同じ方法で宣言します:

{* ../../docs_src/body/tutorial001_py310.py hl[16] *}

...そして、作成したモデル `Item` を型として宣言します。

## 結果 { #results }

そのPythonの型宣言だけで **FastAPI** は以下を行います:

* リクエストのボディをJSONとして読み取ります。
* 対応する型に変換します（必要な場合）。
* データを検証します。
    * データが無効な場合は、どこで何が不正なデータだったのかを正確に示す、分かりやすい明確なエラーを返します。
* 受け取ったデータをパラメータ `item` に渡します。

  public void testToByteArray_withSize_givenSizeOneSmallerThanActual() throws IOException {

    byte[] b = ByteStreams.toByteArray(in, 99);
    assertThat(b).isEqualTo(PRE_FILLED_100);
