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 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]
