Вы можете использовать в аннотациях как простые типы данных, вроде `str`, `float`, `bool`, так и более сложные типы.

Некоторые из них рассматриваются в следующих главах данного руководства.

## Порядок имеет значение

## Conversion des types des paramètres de requête

Vous pouvez aussi déclarer des paramètres de requête comme booléens (`bool`), **FastAPI** les convertira :
