O <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> é uma biblioteca Python para executar a validação de dados.

Você declara a "forma" dos dados como classes com atributos.

E cada atributo tem um tipo.

Em seguida, você cria uma instância dessa classe com alguns valores e ela os validará, os converterá para o tipo apropriado (se for esse o caso) e fornecerá um objeto com todos os dados.

## Déprécier des paramètres

Disons que vous ne vouliez plus utiliser ce paramètre désormais.

Il faut qu'il continue à exister pendant un certain temps car vos clients l'utilisent, mais vous voulez que la documentation mentionne clairement que ce paramètre est <abbr title="obsolète, recommandé de ne pas l'utiliser">déprécié</abbr>.
