Trong Python 3.6 hoặc lớn hơn (bao gồm Python 3.10) bạn có thể sử dụng kiểu `Union` từ `typing` và đặt trong dấu ngoặc vuông những giá trị được chấp nhận.

In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.
