Python期末考试-中心点问题

设有二维平面上的10个点，给定这些点的坐标，找出中心点（即到其他各个点的距离之和最小的点）

这道题也简单，以下是我的代码

import math
def demo():
    d = [0,0,0,0,0,0,0,0,0,0]
    f = [1,9,9,6,0,1,1,1,2,1]
    g = [3,4,2,6,2,2,1,3,1,8]
    for i in range(10):
        for k in range(10):
            d[i] = d[i] + math.sqrt((f[k] - f[i]) ** 2 +(g[k] - g[i]) ** 2)
    s = d[0]
    m = 0
    for i in range(10):
        print("点(",f[i],",",g[i],")""到各点的距离和是:",d[i])
        print("############################")
        if d[i] < s:
            s = d[i]
            m = i
    print("中心点是:(",f[m],",",g[m],")")
demo()
