1.將字符串的時間轉(zhuǎn)換為時間戳方法:a = "2013-10-10 23:40:00"將其轉(zhuǎn)換為時間數(shù)組import timetimeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S")轉(zhuǎn)換為時間戳:timeStamp = int(time.mktime(timeArray))timeStamp == 1381419600 2.字符串格式更改如a = "2013-10-10 23:40:00",想改為 a = "2013/10/10 23:40:00"方法:先轉(zhuǎn)換為時間數(shù)組,然后轉(zhuǎn)換為其他格式timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S")otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray)3.時間戳轉(zhuǎn)換為指定格式日期:方法一:利用localtime()轉(zhuǎn)換為時間數(shù)組,然后格式化為需要的格式,如timeStamp = 1381419600timeArray = time.localtime(timeStamp)otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)otherStyletime == "2013-10-10 23:40:00"方法二:import datetimetimeStamp = 1381419600dateArray = datetime.datetime.utcfromtimestamp(timeStamp)otherStyleTime = dateArray.strftime("%Y-%m-%d %H:%M:%S")otherStyletime == "2013-10-10 23:40:00"4.獲取當(dāng)前時間并轉(zhuǎn)換為指定日期格式方法一:import time獲得當(dāng)前時間時間戳now = int(time.time()) ->這是時間戳轉(zhuǎn)換為其他日期格式,如:"%Y-%m-%d %H:%M:%S"timeArray = time.localtime(timeStamp)otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)方法二:import datetime獲得當(dāng)前時間now = datetime.datetime.now() ->這是時間數(shù)組格式轉(zhuǎn)換為指定的格式:otherStyleTime = now.strftime("%Y-%m-%d %H:%M:%S")5.獲得三天前的時間方法:import timeimport datetime先獲得時間數(shù)組格式的日期threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3))轉(zhuǎn)換為時間戳:timeStamp = int(time.mktime(threeDayAgo.timetuple()))轉(zhuǎn)換為其他字符串格式:otherStyleTime = threeDayAgo.strftime("%Y-%m-%d %H:%M:%S")注:timedelta()的參數(shù)有:days,hours,seconds,microseconds6.給定時間戳,計算該時間的幾天前時間:timeStamp = 1381419600先轉(zhuǎn)換為datetimeimport datetimeimport timedateArray = datetime.datetime.utcfromtimestamp(timeStamp)threeDayAgo = dateArray - datetime.timedelta(days = 3)參考5,可以轉(zhuǎn)換為其他的任意格式了
