* `Set`

* ...など

**ジェネリック型** または **ジェネリクス** と呼びます。

### 型としてのクラス

変数の型としてクラスを宣言することもできます。

例えば、`Person`クラスという名前のクラスがあるとしましょう:

```Python hl_lines="1 2 3"
{!../../../docs_src/python_types/tutorial010.py!}
```

変数の型を`Person`として宣言することができます:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

そして、再び、すべてのエディタのサポートを得ることができます:
