重要的是，通过使用标准的 Python 类型，而且只在一个地方声明（而不是添加更多类、装饰器等），**FastAPI** 会为你完成大量工作。

如果你已经读完所有教程，又回来想进一步了解类型，一个不错的资源是 [`mypy` 的“速查表”](https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html)。

## 特殊な型とバリデーション { #special-types-and-validation }

`str`や`int`、`float`などの通常の単数型の他にも、`str`を継承したより複雑な単数型を使うこともできます。

すべてのオプションをみるには、[Pydantic の型の概要](https://docs.pydantic.dev/latest/concepts/types/)を確認してください。次の章でいくつかの例をみることができます。

例えば、`Image`モデルのように`url`フィールドがある場合、`str`の代わりにPydanticの`HttpUrl`のインスタンスとして宣言することができます:

 * <h3>Views</h3>
 *
 * <p>Much of the power of the multimap API comes from the <i>view collections</i> it provides.
 * These always reflect the latest state of the multimap itself. When they support modification, the
 * changes are <i>write-through</i> (they automatically update the backing multimap). These view
 * collections are:

 * <ul>

N'oubliez pas, le point le plus important est : essayez d'être aimable. Les gens viennent avec leurs frustrations et, dans bien des cas, ne posent pas la question de la meilleure façon, mais faites de votre mieux pour rester aimable. 🤗
