Параметр `name` определён как `Optional[str]`, но он **не необязательный** — вы не можете вызвать функцию без этого параметра:

```Python
say_hi()  # О нет, это вызывает ошибку! 😱
```

Параметр `name` всё ещё **обязателен** (не *optional*), потому что у него нет значения по умолчанию. При этом `name` принимает `None` как значение:

```Python
say_hi(name=None)  # Это работает, None допустим 🎉
```
