Usar `str | None` em vez de apenas `str` permitirá que o editor o ajude a detectar erros em que você poderia estar assumindo que um valor é sempre um `str`, quando na verdade ele também pode ser `None`.

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

Você também pode declarar uma classe como o tipo de uma variável.
