Python's f-strings provide a readable way to interpolate and format strings. They're readable, concise, and less prone to error than traditional string interpolation and formatting tools, such as the .format() method and the modulo operator (%). F-string
实现更灵活的功能：```pythonclass MyNumber:def __mod__(self, other):return self.value % othernum = MyNumber()num.value = 10print(num % 3) 输出 1```四、常见问题及解决办法 1. `TypeError: not all arguments converted during string formatting`原因：占位符数量与传入变量不匹配。
