#### `Dict`

`dict`を宣言するためには、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.py hl[1,4] *}


つまり:

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

#### `Optional`

また、`Optional`を使用して、変数が`str`のような型を持つことを宣言することもできますが、それは「オプション」であり、`None`にすることもできます。
