Una de las principales funcionalidades necesitadas por los sistemas API es la "<abbr title="también llamada marshalling, conversión">serialización</abbr>" de datos, que consiste en tomar datos del código (Python) y convertirlos en algo que pueda ser enviado a través de la red. Por ejemplo, convertir un objeto que contiene datos de una base de datos en un objeto JSON. Convertir...

That means that any value read in Python from an environment variable will be a `str`, and any conversion to a different type or any validation has to be done in code.
