Usar `str | None` en lugar de solo `str` te permitirá al editor ayudarte a detectar errores donde podrías estar asumiendo que un valor siempre es un `str`, cuando en realidad también podría ser `None`.

### Clases como tipos { #classes-as-types }

También puedes declarar una clase como el tipo de una variable.
