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 isA=πr². In case you have the diameter of the circle, the formulaA=1/4πd2has to be used. There is another formula with circumfe...
Python Code:# Import the 'pi' constant from the 'math' module to calculate the area of a circle from math import pi # Prompt the user to input the radius of the circle r = float(input("Input the radius of the circle : ")) # Calculate the area of the circle using the formula: ...
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...
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。
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 ...
