This tutorial explains how to create a simple python program to find area of a circle. In order to find out the area of a circle in Python, you have to know the radius of the circle. The formula for determining the area of a circle is A=πr². In case
提示 在代码清单3-2中,第1～3行是CalCircleArea函数的定义,其只有一个参数r,表示要计算面积的圆的半径。第4～6行是CalRectArea函数的定义,其有两个参数a和b(多个形参需要用逗号分隔),表示要计算面积的长方形的两个边长。
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...
Input the radius of the circle : 1.1 The area of the circle with radius 1.1 is: 3.8013271108436504 Explanation:The said code calculates the area of a circle based on the radius entered by the user. The code uses the "math" module's pi constant and the "input" function to get the radiu...

请简述Python中的继承机制。设计一个Circle(圆)类,该类中包括属性radius(半径),还包括___()、get___area()(求面积)共方法。设计完成后,创建Circle类的对象求周长和面积的功能。相关知识点: 试题来源: 解析 init#perimeter()(求周长)和get 反馈 收藏 ...
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,...
