datetime模块

当前日期

datetime.date.today()

datetime.date(2020, 4, 24)

转换元祖

>>> datetime.date.timetuple(datetime.date.today())

time.struct_time(tm_year=2020, tm_mon=4, tm_mday=24, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=4, tm_yday=115, tm_isdst=-1)

当前时间，精确至毫秒

>>> datetime.datetime.now()

datetime.datetime(2020, 4, 24, 10, 54, 20, 538999)

时间差

>>> t1 = datetime.datetime.now()

>>> datetime.timedelta(days=3)

datetime.timedelta(days=3)

>>> t1 - datetime.timedelta(days=3)

datetime.datetime(2020, 4, 21, 10, 57, 26, 181212)

>>> t1 - datetime.timedelta(days=3,minutes=5)

datetime.datetime(2020, 4, 21, 10, 52, 26, 181212)

替换

>>> t1

datetime.datetime(2020, 4, 24, 10, 57, 26, 181212)

>>> t1.replace(year=2015)

datetime.datetime(2015, 4, 24, 10, 57, 26, 181212)

>>> t1.replace(year=2016,month=3,minute=2)

datetime.datetime(2016, 3, 24, 10, 2, 26, 181212)

帮助调用

help(datetime.datetime())

时区

>>> import pytz

>>> pytz.timezone("Asia/shanghai")

>>> datetime.datetime.now(tz=pytz.timezone("Asia/shanghai"))

datetime.datetime(2020, 4, 24, 11, 14, 47, 215302, tzinfo=)

# 中国所拥有的时区

>>> pytz.country_timezones('cn')

['Asia/Shanghai', 'Asia/Urumqi']
