Dans de nombreux cas, votre application peut avoir besoin de paramètres ou de configurations externes, par exemple des clés secrètes, des identifiants de base de données, des identifiants pour des services d'e-mail, etc.

La plupart de ces paramètres sont variables (peuvent changer), comme les URL de base de données. Et beaucoup peuvent être sensibles, comme les secrets.

    * Strings (`str`) mit definierter minimaler und maximaler Länge.
    * Zahlen (`int`, `float`) mit Mindest- und Maximalwerten, usw.

* Validierung für mehr exotische Typen, wie:
    * URL.
    * E-Mail.
    * UUID.
    * ... und andere.

Die gesamte Validierung übernimmt das gut etablierte und robuste **Pydantic**.

Em muitos casos, sua aplicação pode precisar de configurações externas, por exemplo chaves secretas, credenciais de banco de dados, credenciais para serviços de e-mail, etc.

A maioria dessas configurações é variável (pode mudar), como URLs de banco de dados. E muitas podem ser sensíveis, como segredos.

Por esse motivo, é comum fornecê-las em variáveis de ambiente lidas pela aplicação.
