常见操作：
时间戳转iso
>>> times = 1605087051 >>> datetime.date.fromtimestamp(times).isoformat() '2020-11-11'
iso转时间戳
>>> times = '2020-11-11' >>> datetime.datetime.strptime(times, '%Y-%m-%d').timestamp() 1602259200.0
timedelta
表示两个
date对象或者time对象,或者datetime对象之间的时间间隔，精确到微秒。
可用于两个datetime对象的相加减运算
>>> d1 = datetime.timedelta(days=10) >>> d1 datetime.timedelta(10) >>> datetime.datetime(2020, 1, 1) + d1 datetime.datetime(2020, 1, 11, 0, 0)
date
初始化
>>> from datetime import date
>>> date(1994, 12, 31)
datetime.date(1994, 12, 31)
>>> date.fromisoformat('2019-12-04')
datetime.date(2019, 12, 4)
>>> import time
>>> date.fromtimestamp(time.time())
datetime.date(2020, 11, 11)
datetime
datetime与date用法相近
>>> datetime.datetime.fromtimestamp(time.time()) datetime.datetime(2020, 11, 12, 14, 33, 5, 33660) >>> str(datetime.datetime.fromtimestamp(time.time())) '2020-11-12 14:35:15.213926'
