A common need in data analysis is finding the absolute value of a set of numbers quickly. Python offers an easy, built-in function for performing this task, theabs(). The absolute value function allowsPython programmersto obtain the magnitude of a number, regardless of its sign, essentially ...
我们首先定义一个求绝对值的函数absolute_value(num),参数为num,函数语句块为当参数大于等于 0时,返回参数值num,当参数小于 0 时,返回参数值-num; 第二步为打印调用函数absolute_value(num)值,当参数值为 2 时,absolute_value(2)调用返回 2;当参数值为 -4 时,absolute_value(-4)调用返回参数值 --4,即...

Return the absolute value of the argument. #返回参数的绝对值 这里我们有内置函数help()来查看abs()的功能。这里又给大家介绍了一种内置函数help()的使用方法。不知道某个内置函数的用法,直接敲下help()查询下就OK了! 2、dir()可以快速的查看对象提供了那些方法,如查看列表的方法,见截图: ...
In this tutorial, you'll learn how to calculate the absolute value in Python using the built-in abs() function. You'll also implement the corresponding mathematical formulas from scratch. Finally, you'll change the behavior of abs() in your own classes b
