Conforme o Python evolui, **novas versões** chegam com suporte melhorado para esses type annotations, e em muitos casos, você não precisará nem importar e utilizar o módulo `typing` para declarar os type annotations.

Se você pode escolher uma versão mais recente do Python para o seu projeto, você poderá aproveitar isso ao seu favor.
