【模拟】回文日期

题目

我的代码

import datetime
ipt = input()
begin = datetime.datetime(int(ipt[0:4]), int(ipt[4:6]), int(ipt[6:8]))
flag1=0
flag2=0
while True:
  if flag1==1 and flag2==1:
    break
  begin += datetime.timedelta(days=1)
  date = str(begin.year)
  if begin.month<10:
    date = date + "0"
  date = date + str(begin.month)
  if begin.day<10:
    date = date + "0"
  date = date + str(begin.day)
  
  if date == date[::-1] and flag1==0:
      print(date)
      flag1=1
  if date == date[::-1] and date[0]==date[2]==date[5]==date[7] and date[1]==date[3]==date[4]==date[6]:
      print(date)
      flag2=1
​

使用datetime上大分，防止非法日期的出现，主要要记住datetime的加减：begin += datetime.timedelta(days=1)
