Python类 爱你一辈子到底是多久

想知道解答思路呀
可以一天一天循环吗？还是说按年份月的天数计算比较方便呢

import datetime

class Date():
    def __init__(self, y, m, d):
        self.y = y
        self.m = m
        self.d = d

    def add_one_day(self, d):
        a = datetime.datetime(self.y, self.m, self.d) + datetime.timedelta(days=d)
        self.y = a.year
        self.m = a.month
        self.d = a.day

y,m,d = map(int,(input().split()))
day = Date(y,m,d)
day.add_one_day(10000)
print(f'{day.y}/{day.m}/{day.d}')

定义一个列表days，里面存放平年每个月的天数
如果是闰年，day[1]+=1

给个例子做参考

class Date:
    def __init__(self,y,m,d):
        self.y = y
        self.m = m
        self.d = d
    def add_one_day(self):
        md_lst = [31,28,31,30,31,30,31,31,30,31,30,31]
        if (self.y%4==0 and self.y%100!=0) or self.y%400==0:
            md_lst[1] = 29
        if self.d==md_lst[self.m-1]:
            self.d = 1
            if self.m==12:
                self.y += 1
                self.m = 1
            else:
                self.m +=1
        else:
            self.d += 1
if __name__ == '__main__':
    y,m,d = [int(x) for x in input().split()]
    date = Date(y,m,d)
    for i in range(10000):
        date.add_one_day()
    print(f'{date.y}/{date.m}/{date.d}')
