python的强大就在于有非常多好用的库，有现成的解决方案就不要重复造轮子了

要达到看到一个问题就能反映上来可以直接用哪个库里现成的方法来解决是要把所有的库都过一遍？

def M_T(spare = 0 , M = 1 , day = 20):
                count = 0
                for each_day in range(0,(M - 1)):
                                if((M - 1) > 0):
                                                count += today[each_day]
                if(spare == 0):
                                count += day
                                print('这是这年的第%d天' % count)
                elif(spare == 1):
                                count += day + 1
                                print('这是这年的第%d天' % count)
                elif(M - 1) == 0:
                                print('这是这年的第%d天' % day)

可以放到闰年里了
>>> M_T()
这是这年的第20天
>>>

我的解答！

判读润年有误.:)
(年能整除4且不能整除100  )或 (年能整除 400 ) 是润年!
