那年春，夫子去国游历，遇桃山美酒，遂寻径登山赏桃品酒，一路摘花饮酒而行，始切一斤桃花，饮一壶酒，后夫子惜酒，故再切一斤桃花，只饮半壶酒，再切一斤桃花，饮半半壶酒，如是而行……至山顶，夫子囊中酒尽，惘然四顾，淡问诸生：今日切了几斤桃花，饮了几壶酒？

答案很显然是夫子饮酒两壶斩尽满山桃花，但是换个玩法，用代码怎么算呢？

import time
wine=1
blossom=1
drink_sum=1
while True:
    print('夫子折花%d斤，饮酒%.50f葫' % (blossom, drink_sum))
    drink_sum =drink_sum+ wine / 2
    wine=wine/2
    blossom+=1
    time.sleep(0.01)
    if(drink_sum==2):
        print('夫子已斩尽满山桃花，所带酒水已饮完!')
        break

 结果如下：
