在f-字符串调试中,您还可以执行数学运算,就像在最后一行中看到的那样。 x = 10 y = 20 print(f"x = {x}, y = {y}") print(f"{x = }, {y = }") # math operations print(f"{x * y = }") 2.数字格式化(Number formatting) 使用f-字符串,您可以对字符串执行多种格式化和转换操作。以下...
f-string 在Python中,print(f’') 是一种格式化字符串的便捷方式,称为 f-string(格式化字符串字面量)。f-string 是在 Python 3.6 中引入的,它提供了一种非常直观和高效的方法来嵌入表达式到字符串字面量中。 基本语法 f-string 的基本语法非常简单,只需在字符串前加上一个小写的 f 或大写的 F,然后在...
f-string,亦称为格式化字符串常量(formatted string literals),是Python3.6新引入的一种字符串格式化方法,该方法源于PEP 498 – Literal String Interpolation,主要目的是使格式化字符串的操作更加简便。f-string在形式上是以 f 或 F 修饰符引领的字符串(f'xxx' 或 F'xxx'),以大括号 {} 标明被替换的字段;f-s...
