使用timedelta
timedelta是datetime中的一个对象，该对象表示两个时间的差值。
构造函数：
datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)
其中参数都是可选，默认值为0
1 millisecond = 1000 microseconds
1 minute = 60 seconds
1 hour = 3600 seconds
1 week = 7 days
import datetime# 获取当前时间now = datetime.datetime.now()# 获取今天零点zeroToday = now - datetime.timedelta(hours=now.hour, minutes=now.minute, seconds=now.second, microseconds=now.microsecond)# 获取23:59:59lastToday = zeroToday + datetime.timedelta(hours=23, minutes=59, seconds=59)# 获取前一天的当前时间yesterdayNow = now - datetime.timedelta(hours=23, minutes=59, seconds=59)# 获取明天的当前时间tomorrowNow = now + datetime.timedelta(hours=23, minutes=59, seconds=59)print('时间差', datetime.timedelta(hours=23, minutes=59, seconds=59))print('当前时间', now)print('今天零点', zeroToday)print('获取23:59:59', lastToday)print('昨天当前时间', yesterdayNow)print('明天当前时间', tomorrowNow)输出：时间差 23:59:59当前时间 -08-19 10:16:32.510070今天零点 -08-19 00:00:00获取23:59:59 -08-19 23:59:59昨天当前时间 -08-18 10:16:33.510070明天当前时间 -08-20 10:16:31.510070
