python 100题04

题目：输入某年某月某日，判断这一天是这一年的第几天？

判断某一年是否是闰年方法：

• 能被4整除但不能被10整除

• 能被400整除

  Dates = {}
  count_day = 0
  Dates['year'] = int(input("please input the year:"))
  Dates['mouth'] = int(input("and the mouth:"))
  Dates['day'] = int(input("and the day:"))
  mouth = [1,2,3,4,5,6,7,8,9,10,11,12]
  day = [31,28,31,30,31,30,31,31,30,31,30,31]
  for i in range(13):
   if i < Dates['mouth'] - 1:
    count_day += day[i]
   elif i == Dates['mouth']:
    count_day += Dates['day']
  if Dates['year'] % 4 == 0 and Dates['year'] % 10 != 0:
   count_day += 1
  
  print(f"On {Dates['year']} - {Dates['mouth']} - {Dates['day']}")
  print(f"the year have passed {count_day}")
