【单选题】题目: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:\n'))month = int(input('month:\n'))day = int(input('day:\n'))months = [0,31,59,90,120,...
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))
【简答题】假设 a=5, b=2, c=4 ,以下表达式的值依次为: 。 (1) a % b * c && c % b * a (2) b % c * a && a % c * b (3) a % b * c || c % b * a (4) b % c * a || a % c * b
