Python 3.14引入了全新的t-string语法，提供了一种创建可重用模板的机制，与f-string的即时求值特性形成了重要补充。

Furthermore, Python contains the notion of "slice-notation," meaning that the programmer can chose small sections of the string, called "substrings" to manipulate as well.

This change can make it easier for developers to write and read code that uses F strings. Python 3.12 also brings changes related to types and type annotations.
