形参只能在函数中使用,其作用是接收函数调用时传入的参数值(即后面要介绍的实参),并在函数中参与运算。 下面的代码定义了两个函数:计算圆面积的函数CalCircleArea和计算长方形面积的函数CalRectArea。 代码清单3-2 圆面积函数和长方形面积函数的定义 1 def CalCircleArea(r): #定义名为CalCircleArea的函数 2 s=...

有了函数,我们就不再每次写s = 3.14 * x * x,而是写成更有意义的函数调用 s = area_of_circle(x),而函数 area_of_circle 本身只需要写一次,就可以多次调用。 抽象是数学中非常常见的概念。举个例子: 计算数列的和,比如:1 + 2 + 3 + ... + 100,写起来十分不方便,于是数学家发明了求和符号∑,可...

getcircleArea函数求圆的面积python 定义函数getCircleArea(r),可以对指定r计算圆面积。计算公式math库的pi*r*r。 定义函数get_rList(n),功能:输入n个值放入列表并将列表return。 输入n,调用get_rList(n)获得列表rList。 遍历rList,对每个元素调用getCircleArea,并按格式输出。 注意:需导入程序中所需要的库,...
Largest Triangle Area in Python - Suppose we have a list of points on a plane. We have to find the area of the largest triangle that can be formed by any 3 of the points.So, if the input is like [[0,0],[0,1],[1,0],[0,2],[2,0]], then the output will be 2T
