1. round函数的基本用法 round函数是Python内置的一个函数，用于将一个数字进行四舍五入。其基本用法如下：round(number[, ndigits])其中，number是要进行四舍五入的数字，ndigits是保留的小数位数，默认值为0。如果ndigits为正数，则表示保留的小数位数；如果ndigits为负数，则表示将number四舍五入到最近的10、...
一、round函数的基本用法 round函数的基本语法如下: round(number[, ndigits]) 其中,number是要进行四舍五入的数字,ndigits是保留的小数位数。如果ndigits省略,则默认为0。 例如,我们可以使用以下代码将3.1415926四舍五入保留两位小数: ```python >>> round(3.1415926, 2) 3.14 ``` 在这个例子中,我们将3.14159...
