python中的time时间模块使用知识
python实现简单日期工具类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：
