基础python的题，但是我不会

感觉挺难的，但是同学他们好像都听懂了，应该是用什么函数来的，

import math

def get_rList(n):
    rList = []
    for _ in range(n):
        rList.append(int(input(">>>")))
    return rList

def getCircleArea(r):
    return math.pi * r * r

n = int(input(">>>"))
rlist = get_rList(n)
for i in rlist:
    print(f"半径为{i}的圆的面积为：{getCircleArea(i):.3f}")
    
print(f"rlist={str(rlist)}")
