1. datatime.date.today() 当前日期
>>> import datetime >>> datetime.date.today() datetime.date(2016, 3, 13)
2. datetime.datetime.now() 当前时间
>>> datetime.datetime.now()
datetime.datetime(2016, 3, 13, 21, 21, 32, 523934)3. datetime.datetime.today() 当前时间
>>> datetime.datetime.today()
datetime.datetime(2016, 3, 13, 21, 22, 0, 85805)4. datetime.date.fromtimestamp() 将时间戳日期输出
>>> datetime.date.fromtimestamp(1457877369.650549)
datetime.date(2016, 3, 13)5. datetime.datetime.fromtimestamp() 将时间戳输出
>>> datetime.datetime.fromtimestamp(1457877369.650549)
datetime.datetime(2016, 3, 13, 21, 56, 9, 650549)6. timetuple() 转换为strucktime
>>> datetime.datetime.now().timetuple() time.struct_time(tm_year=2016, tm_mon=3, tm_mday=13, tm_hour=22, tm_min=1, tm_se c=25, tm_wday=6, tm_yday=73, tm_isdst=-1)
7. replace() 替换日期，传什么替换什么
>>> datetime.datetime.now().replace(2014, 9, 12)
datetime.datetime(2014, 9, 12, 22, 3, 9, 229790)8. strptime()
>>> datetime.datetime.strptime("21/11/06 16:30", "%d/%m/%y %H:%M") datetime.datetime(2006, 11, 21, 16, 30)
9. 日期时间的加减
new_time = datetime.datetime.now() + datetime.timedelta(days=10) #当前时间+10天 new_time = datetime.datetime.now() + datetime.timedelta(days=-10) new_time = datetime.datetime.now() - datetime.timedelta(days=10) #这两个都是当前时间-10天 new_time = datetime.datetime.now() - datetime.timedelta(hours=10) new_time = datetime.datetime.now() - datetime.timedelta(seconds=10)
