python def area(radius): """ 计算并返回给定半径的圆的面积。 Args: radius (float): 圆的半径 Returns: float: 圆的面积 """ 3. 在函数内计算圆的面积 在函数内部,我们使用公式πr²来计算圆的面积,其中π可以使用math.pi来获取。 python area_of_circle = math.pi * (radius ** 2) 4. 返...
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...

Write a Python program that calculates the area of a circle based on the radius entered by the user. Python: Area of a Circle In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal...
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,...
