datetime模組
當前日期
datetime.date.today()
datetime.date(2020,4,24)
轉換元祖
>>> 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)
當前時間，精確至毫秒
>>> datetime.datetime.now()
datetime.datetime(2020,24,10,54,20,538999)
時間差
>>> t1 = datetime.datetime.now() >>> datetime.timedelta(days=3) datetime.timedelta(days=3) >>> t1 - datetime.timedelta(days=3) datetime.datetime(2020,21,57,26,181212) >>> t1 - datetime.timedelta(days=3,minutes=5) datetime.datetime(2020,52,181212)
替換
>>> t1 datetime.datetime(2020,181212) >>> t1.replace(year=2015) datetime.datetime(2015,181212) >>> t1.replace(year=2016,month=3,minute=2) datetime.datetime(2016,3,2,181212)
幫助呼叫
help（datetime.datetime()）
時區
>>> import pytz
>>> pytz.timezone("Asia/shanghai")
<DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD>
>>> datetime.datetime.now(tz=pytz.timezone("Asia/shanghai"))
datetime.datetime(2020,11,14,47,215302,tzinfo=<DstTzInfo 'Asia/Shanghai' CST+8:00:00 STD>)
# 中國所擁有的時區
>>> pytz.country_timezones('cn')
['Asia/Shanghai','Asia/Urumqi']
# 美國所擁有的時區
>>> pytz.country_timezones('us')
