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>.

Trong Python 3.10 cũng có một **cú pháp mới** mà bạn có thể đặt những kiểu giá trị khả thi phân cách bởi một dấu <abbr title='cũng được gọi là "toán tử nhị phân"'>sổ dọc (`|`)</abbr>.
