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...
The program prompts the user to enter the circle radius in the example usage section. It then creates an instance of the Circle class using the given radius and calculates its area and perimeter. The calculated values are then printed. Flowchart: Python Code Editor: Python OOP Exercises Home....

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 ...
Pythoncirclearea函数 python circle函数参数 3.2 参数列表与返回值 对于代码清单3-1中实现的CalCircleArea函数,只能进行半径为3的圆面积的计算,而无法用于计算其他半径的圆的面积。另外,在计算圆面积后,只是通过print函数将计算结果输出到屏幕上,而无法使用该计算结果再去做其他运算。这里将要介绍的参数列表与返回值...
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,...
