#### Uso de `Union` u `Optional`

Si estás usando una versión de Python inferior a 3.10, aquí tienes un consejo desde mi punto de vista muy **subjetivo**:

## O principal `FastAPI`

Agora, vamos ver o módulo em `app/main.py`.

Aqui é onde você importa e usa a classe `FastAPI`.

Este será o arquivo principal em seu aplicativo que une tudo.

E como a maior parte de sua lógica agora viverá em seu próprio módulo específico, o arquivo principal será bem simples.
