Python计算一球从100米高度自由落下？

high = 100n = 10high_all = 0 #第n次落地时走过的长度high_each = 0 #每次落地的高度def ball_lands(n): global high_all, high_each, high #小球第一次落地时 if n == 0: high_each = high high_all += high_each #print('1', high_each, high_all) return high_each #从小球第n次落地往前推 high_each = high * (1 / 2) ** n print(u'第%d次小球弹起的高度为：%.2f' %(n, high_each)) high_all += high_each * 2 #print('2', high_each, high_all) ball_lands(n - 1)ball_lands(n)print(u'小球落地%d次，共经过%.2f米。' % (n,high_all))
