本文实例为大家分享了python实现简单日期工具类的具体代码，供大家参考，具体内容如下

import datetimeimport timeDATETIME_FORMAT = "%Y-%m-%d %H:%M:%S"TIME_FORMAT = "%H:%M:%S"#当前毫秒数def curMilis(): return int(time.time() * 1000)#当前秒数def curSeconds(): return int(time.time())#当前日期 格式%Y-%m-%d %H:%M:%Sdef curDatetime(): return datetime.datetime.strftime(datetime.datetime.now(),DATETIME_FORMAT)#当前日期 格式%Y-%m-%ddef curDate(): return datetime.date.today()#当前时间 格式%Y-%m-%ddef curTime(): return time.strftime(TIME_FORMAT)#秒转日期def secondsToDatetime(seconds): return time.strftime(DATETIME_FORMAT,time.localtime(seconds))#毫秒转日期def milisToDatetime(milix): return time.strftime(DATETIME_FORMAT,time.localtime(milix//1000))#日期转毫秒def datetimeToMilis(datetimestr): strf = time.strptime(datetimestr,DATETIME_FORMAT) return int(time.mktime(strf)) * 1000#日期转秒def datetimeToSeconds(datetimestr): strf = time.strptime(datetimestr,DATETIME_FORMAT) return int(time.mktime(strf))#当前年def curYear(): return datetime.datetime.now().year#当前月def curMonth(): return datetime.datetime.now().month#当前日def curDay(): return datetime.datetime.now().day#当前时def curHour(): return datetime.datetime.now().hour#当前分def curMinute(): return datetime.datetime.now().minute#当前秒def curSecond(): return datetime.datetime.now().second#星期几def curWeek(): return datetime.datetime.now().weekday()#几天前的时间def nowDaysAgo(days): daysAgoTime = datetime.datetime.now() - datetime.timedelta(days = days) return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())#几天后的时间def nowDaysAfter(days): daysAgoTime = datetime.datetime.now() + datetime.timedelta(days = days) return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())#某个日期几天前的时间def dtimeDaysAgo(dtimestr,days): daysAgoTime = datetime.datetime.strptime(dtimestr,DATETIME_FORMAT) - datetime.timedelta(days = days) return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())#某个日期几天前的时间def dtimeDaysAfter(dtimestr,days): daysAgoTime = datetime.datetime.strptime(dtimestr,DATETIME_FORMAT) + datetime.timedelta(days = days) return time.strftime(DATETIME_FORMAT,daysAgoTime.timetuple())secondStamp = curSeconds()print("当前秒：",secondStamp)milisStamp = curMilis()print("当前毫秒：",milisStamp)curdTime = curDatetime()print("当前时间：",curdTime)curDate = curDate()print("当前日期：",curDate)curT = curTime()print("当前时刻：",curT)stdtime = secondsToDatetime(secondStamp)print("秒转时间：",stdtime)mtdtime = milisToDatetime(milisStamp)print("毫秒转时间：",mtdtime)dtimetm = datetimeToMilis(mtdtime)print("时间转毫秒：",dtimetm)dtimets = datetimeToSeconds(mtdtime)print("时间转秒：",dtimets)year = curYear()print("年：",year)month = curMonth()print("月：",month)day = curDay()print("日：",day)hour = curHour()print("时：",hour)minute = curMinute()print("分：",minute)second = curSecond()print("秒：",second)week = curWeek()print("星期：",week)

输出结果如下：

当前秒： 1518341913当前毫秒： 1518341913403当前时间： 2018-02-11 17:38:33当前日期： 2018-02-11当前时刻： 17:38:33秒转时间： 2018-02-11 17:38:33毫秒转时间： 2018-02-11 17:38:33时间转毫秒： 1518341913000时间转秒： 1518341913年： 2018月： 2日： 11时： 17分： 38秒： 33星期： 6[Finished in 0.2s]
