```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

FastAPI est suffisamment intelligent (en fait, Pydantic l’est) pour comprendre que, même si `description`, `tax` et `tags` ont les mêmes valeurs que les valeurs par défaut, elles ont été définies explicitement (au lieu d'être prises depuis les valeurs par défaut).

Elles seront donc incluses dans la réponse JSON.

Ahora revisemos esos cambios paso a paso.

## Esquema de seguridad OAuth2 { #oauth2-security-scheme }

El primer cambio es que ahora estamos declarando el esquema de seguridad OAuth2 con dos scopes disponibles, `me` y `items`.

El parámetro `scopes` recibe un `dict` con cada scope como clave y la descripción como valor:

    assertThat(data2.streamId).isEqualTo(3)
    assertArrayEquals("fghi".toByteArray(), data2.data)
  }

  /**
   * Confirm that we account for discarded data frames. It's possible that data frames are in-flight
   * just prior to us canceling a stream.
   */
  @Test fun discardedDataFramesAreCounted() {
    // Write the mocking script.
    peer.sendFrame().settings(Settings())

Vous pouvez considérer `APIRouter` comme une « mini `FastAPI` ».

Toutes les mêmes options sont prises en charge.

Tous les mêmes `parameters`, `responses`, `dependencies`, `tags`, etc.

Dans cet exemple, la variable s'appelle `router`, mais vous pouvez la nommer comme vous le souhaitez.

#### Dict { #dict }

`dict` を定義するには、カンマ区切りで 2 つの型パラメータを渡します。

最初の型パラメータは `dict` のキーです。

2 番目の型パラメータは `dict` の値です:

{* ../../docs_src/python_types/tutorial008_py310.py hl[1] *}

つまり:

* 変数 `prices` は `dict` です:
    * この `dict` のキーは `str` 型です（例えば、各項目の名前）。
    * この `dict` の値は `float` 型です（例えば、各項目の価格）。

#### Union { #union }

変数が **複数の型のいずれか** になり得ることを宣言できます。例えば、`int` または `str` です。

        writeTimeout = checkDuration("duration", duration)
      }
