関数のパラメータとして、型ヒントを宣言している主な場所を確認しました。

これは **FastAPI** で使用する主な場所でもあります。

### 単純な型

`str`だけでなく、Pythonの標準的な型すべてを宣言することができます。

例えば、以下を使用可能です:

* `int`
* `float`
* `bool`
* `bytes`

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial005.py!}
```

### 型パラメータを持つジェネリック型

データ構造の中には、`dict`、`list`、`set`、そして`tuple`のように他の値を含むことができるものがあります。また内部の値も独自の型を持つことができます。
