* No lugar, ✨ **use `Union[SomeType, None]`** ✨.

Ambos são equivalentes, e no final das contas, eles são o mesmo. Mas eu recomendaria o `Union` ao invés de `Optional` porque a palavra **Optional** parece implicar que o valor é opcional, quando na verdade significa "isso pode ser `None`", mesmo que ele não seja opcional e ainda seja obrigatório.

Eu penso que `Union[SomeType, None]` é mais explícito sobre o que ele significa.
