B1028 人口普查（python）

这判别条件有点捉急，我还没想到更好的判断的存储格式
一个测试点超时，一个输出格式错误？

n = int(input())
ls = []
for i in range(n):
    ls.append(input().split(' '))
M = [2014, 9, 6]
m = [1814, 9, 6]
M_name = ''
m_name = ''
cnt = 0
for s in ls:
    d = list(map(int, s[-1].split('/')))
    if 1814 < d[0] < 2014 or \
       (d[0] == 1814 and d[1] > 9) or \
       (d[0] == 1814 and d[1] == 9 and d[2] >= 6) or \
       (d[0] == 2014 and d[1] < 9) or \
       (d[0] == 2014 and d[1] == 9 and d[2] <=6):
        cnt += 1
