Python datetime模块使用方法小结
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
>>>importpytz
>>>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']
#美国所拥有的时区
>>>pytz.country_timezones('us')
['America/New_York','America/Detroit','America/Kentucky/Louisville','America/Kentucky/Monticello','America/Indiana/Indianapolis','America/Indiana/Vincennes',
'America/Indiana/Winamac','America/Indiana/Marengo','America/Indiana/Petersburg','America/Indiana/Vevay','America/Chicago','America/Indiana/Tell_City','Ame

>>>datetime.datetime.now(tz=pytz.timezone("Asia/shanghai"))#上海时区
datetime.datetime(2020,4,24,11,23,14,871634,tzinfo=)
>>>datetime.datetime.now(tz=pytz.timezone("America/New_York"))#纽约时区
datetime.datetime(2020,4,23,23,23,32,743094,tzinfo=)
>>>datetime.datetime.now(tz=pytz.timezone("Asia/Saigon"))#胡志明市越南
datetime.datetime(2020,4,24,10,24,53,456136,tzinfo=)
