The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

Então, você pode adicionar dados extras ao esquema gerado automaticamente.

Por exemplo, você poderia decidir ler e validar a requisição com seu próprio código, sem usar as funcionalidades automáticas do FastAPI com o Pydantic, mas ainda assim querer definir a requisição no esquema OpenAPI.

Você pode fazer isso com `openapi_extra`:

## Criar e Usar Variáveis de Ambiente { #create-and-use-env-vars }

Você pode **criar** e usar variáveis de ambiente no **shell (terminal)**, sem precisar do Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Você pode criar uma variável de ambiente MY_NAME com
$ export MY_NAME="Wade Wilson"
