変数`item`はリスト`items`の要素の一つであることに注意してください。

それでも、エディタはそれが`str`であることを知っていて、そのためのサポートを提供しています。

#### `Tuple` と `Set`

`tuple`と`set`の宣言も同様です:

```Python hl_lines="1 4"
{!../../docs_src/python_types/tutorial007.py!}
```

つまり:

* 変数`items_t`は`int`、`int`、`str`の3つの項目を持つ`tuple`です

* 変数`items_s`はそれぞれの項目が`bytes`型である`set`です。

#### `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。
