time.time()返回的是一个浮点数,单位为秒。但strftime处理的类型是time.struct_time,实际上是一个tuple
>>> import time
>>> print time.time()
1533097203.55
>>> ac = time.localtime(time.time())
time.struct_time(tm_year=2018, tm_mon=8, tm_mday=1, tm_hour=12, tm_min=20, tm_sec=20, tm_wday=2, tm_yday=213, tm_isdst=0)
>>> time.strftime('%Y-%m',ac)
'2018-08'
import datatime
>>> datetime.datetime.today()
datetime.datetime(2018, 8, 1, 14, 3, 19, 675435)
>>> dl=datetime.datetime.today()
>>> dl
datetime.datetime(2018, 8, 1, 14, 3, 31, 39252)
>>> print dl
2018-08-01 14:03:31.039252
>>> datetime.datetime.today()
datetime.datetime(2018, 8, 1, 14, 3, 59, 669356)
>>> dy = dl.strftime('%y--%m')
>>> dy
'18--08'
>>> data = dl.date()
>>> print data
2018-08-01
>>> tim = dl.time()
>>> print tim
14:03:31.039252
print("现在是 {}年 {}月 {}日".format(data.year, data.month, data.day))
现在是 2018年 8月 1日
kprq = kprq.strftime('%Y年%m月%d日')?
