getCircleArea(r)#r代表整数半径 get_rList(n)#n代表在函数中输入n个值放入列表。 裁判测试程序样例: /*请在这里填写答案*/ n=int(input()) rList=get_rList(n) for e in rList: print(type(rList)) 输入样例: 输出样例: 3.142 12.566 28.274 import math def getCircleArea(r):return math.pi*...
当代码出现有规律的重复的时候,你就需要当心了,每次写3.14 * x * x不仅很麻烦,而且,如果要把3.14改成3.14159265359的时候,得全部替换。 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...

编写一个类`Circle`,包含两个属性`radius`和`color`,以及四个方法`get_area()`、`get_circumference()`、`get_diameter()`和`print_info()`,分别用于计算圆面积、圆周长、圆直径,并打印出圆的半径和颜色。代码如下,请补全代码。class Circle: def __init__(self, ra
You can get to the Science Museum by going on the London Underground from Waterloo on the Jubilee line to Westminster. Then take the Circle or the District line to South Kensington. When you walk out take a look around you and you should see it. What to bring: at least two bottles of...
