## まとめ

`Query`と`Path`（そしてまだ見たことない他のもの）では、[クエリパラメータと文字列の検証](query-params-str-validations.md){.internal-link target=_blank}と同じようにメタデータと文字列の検証を宣言することができます。

また、数値のバリデーションを宣言することもできます:

* `gt`: より大きい（`g`reater `t`han）
* `ge`: 以上（`g`reater than or `e`qual）
* `lt`: より小さい（`l`ess `t`han）

Para usar `EmailStr`, primero instala <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install email-validator
```

o con:

```console
$ pip install "pydantic[email]"
```

///

Cuando instalas FastAPI con `pip install "fastapi[standard]"` viene con el grupo `standard` de dependencias opcionales:

Usadas por Pydantic:

* <a href="https://github.com/JoshData/python-email-validator" target="_blank"><code>email-validator</code></a> - para validación de correos electrónicos.

Usadas por Starlette:

* <a href="https://www.python-httpx.org" target="_blank"><code>httpx</code></a> - Requerido si deseas usar el `TestClient`.
