Tham số `name` được định nghĩa là `Optional[str]`, nhưng nó **không phải là tùy chọn**, bạn không thể gọi hàm mà không có tham số:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

Tham số `name` **vẫn được yêu cầu** (không phải là *tùy chọn*) vì nó không có giá trị mặc định. Trong khi đó, `name` chấp nhận `None` như là giá trị:
