## Actualización del Ejemplo { #example-upgrade }

Ahora modifica el archivo `main.py` para recibir un body desde un request `PUT`.

Declara el body usando tipos estándar de Python, gracias a Pydantic.

   * override methods (probably called "unsafeDoForward" and "unsafeDoBackward") with the same
   * signatures as the methods below, rather than overriding the same doForward and doBackward
