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 datetime import time DATETIME_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:%S def curDatetime(): return datetime.datetime.strftime(datetime.datetime.now(),DATETIME_FORMAT) #当前日期 格式%Y-%m-%d def curDate(): return datetime.date.today() #当前时间 格式%Y-%m-%d def 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]
