# Дополнительные типы данных { #extra-data-types }

До сих пор вы использовали простые типы данных, такие как:

* `int`
* `float`
* `str`
* `bool`

Но вы также можете использовать и более сложные типы.

При этом у вас останутся те же возможности, что и до сих пор:

* Отличная поддержка редактора кода.
* Преобразование данных из входящих запросов.
* Преобразование данных для ответа.
* Валидация данных.

この場合、関数パラメータ `q` はオプショナルとなり、デフォルトでは `None` になります。

/// check | 確認

パスパラメータ `item_id` はパスパラメータであり、`q` はそれとは違ってクエリパラメータであると判別できるほど**FastAPI** が賢いということにも注意してください。

///

## クエリパラメータの型変換

`bool` 型も宣言できます。これは以下の様に変換されます:

 The jar file is executable and provides a little tool to display how Maven parses and compares versions:

Display parameters as parsed by Maven (in canonical form) and comparison result:
