    输入某年某年某月某日,判断这一天是这一年的第几天?思路:以3月5日为例,应该先把前两个月的加起来,然后再加上5天即本年的第几天,特殊情况,闰年且输入月份大于3时需考虑多加一天:year = int(input(‘year:’))month = int(input(‘month:’))day = int(input(‘day:’))months = [0,31,59,90,120,151,181,2
    A: (year % 400 == 0) or ((year % 4 == 0) and (year % 100 != 0))
    B: (year % 400 = 0) or ((year % 4 = 0) and (year % 100 != 0))
    C: (year % 400 == 0) and ((year % 4 == 0) and (year % 100 != 0))
    D: (year % 400 == 0) and ((year % 4 == 0) or (year % 100 != 0))
