El parámetro `name` sigue siendo **requerido** (no *opcional*) porque no tiene un valor predeterminado. Aún así, `name` acepta `None` como valor:

```Python
say_hi(name=None)  # Esto funciona, None es válido 🎉
```

La buena noticia es que, una vez que estés en Python 3.10, no tendrás que preocuparte por eso, ya que podrás simplemente usar `|` para definir uniones de tipos:
