使用变量year代表年份，以下表示判断year是否为闰年的布尔表达式是 。 A: (year % 4 == 0) and (not(year % 100 == 0)) or (year % 400 == 0) B: (year % 4 == 0) and (not(year % 400 == 0)) or (year % 100 == 0) C: (year % 4 == 0) and (year % 100 == 0) or (year % 400 == 0) D: (year % 4 == 0) or (not(year % 100 == 0)) and (year % 400 == 0)

题:(拓展)下面哪些表达式能够判断某年year不是闰年。 A: not(( year%4==0 and year%100 !=0 ) or ( year%400==0 )) B: not( year%4==0 and year%100 !=0 ) and not ( year%400==0 ) C: year%4!=0 or year%100 ==0 and ( year%400 !=0 ) D: year%4==0 and year%100 !=0 or ( year%400==0 )

判断某年是否为闰年的表达式正确的是()。 A: year%4==0&&year%100!=0||year%400==0 B: year%4==0&&year%100=0||year%400!=0 C: year%4!=0&&year%100!=0||year%400==0 D: year%4==0&&year%100==0||year%400==0

闰年的判定条件是能被400整除，或者能被4整除但不能被100整除，正确的Python表达式为( )。 A: (year%400==0) or (year%4==0 and year % 100!=0) B: year%400==0 and year%4==0 and year % 100!=0 C: (year//400==0) or (year//4==0 and year//100!=0) D: year//400==0 or year//4==0 and year//100!=0

用变量year表示某一年,判别不是闰年的逻辑表达式有( ). A: (year%4||!(year%100))&&year%400 B: 61519 C: (year%4==0&&year%100!=0)||year%400==0 D: !((year%4==0&&year%100!=0)||year%400==0) E: (year%4!=0||year%100==0)&&year%400!=0
