def say_hi(name: Optional[str]):

```

Параметр `name` визначено як `Optional[str]`, але він не є необов'язковим, ви не можете викликати функцію без цього параметра:

```Python
say_hi()  # О ні, це викликає помилку! 😱
```

Параметр `name` все ще обов'язковий (не «необов'язковий»), тому що не має значення за замовчуванням. Водночас `name` приймає `None` як значення:
