从python中的datetime.strptime输出的分钟和小时

Question

假设：

stime = []
for item in printList1:
    field = item.split()
    request_id.append(field[4])
    stime.append(field[0])
TIME_FORMAT2 = "%H:%M:%S,%f"
s1 = datetime.strptime(stime[0], TIME_FORMAT2)
print s1

输出：

1900-01-01 08:07:01.080000

如何从输出中获得分钟和小时？
