本文提供了一套Python实现的简单日期处理工具类,涵盖当前时间获取、秒与毫秒互转、日期字符串解析及年月日时分秒提取等功能。通过具体代码示例展示如何快速进行时间格式化处理,适用于日常开发中的基础时间操作需求。
Python日期处理工具类实现
本文分享了一个基于Python编写的简易日期处理工具类的具体实现代码,供读者参考学习。
核心功能代码
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)
程序运行后的输出结果如下所示:
