這幾天收集一下時間處理的基本,先作一下筆記;謝謝分享的筆者!!!java
"2013-10-10 23:40:00" ->
"2013/10/10 23:40:00"
{字符串的時間轉換爲時間戳}
a = "2013-10-10 23:40:00" import time timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S") timeStamp = int(time.mktime(timeArray)) print(timeStamp) >> 1381419600
"2013-10-10 23:40:00" ->
"2013/10/10 23:40:00"
{字符串格式修改}
timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S") otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray)
{時間戳轉換爲指定格式日期}
方法一:
利用localtime()轉換爲時間數組,而後格式化爲須要的格式,如
timeStamp = 1381419600 timeArray = time.localtime(timeStamp) otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray) >> "2013-10-10 23:40:00"
方法二:
import datetime timeStamp = 1381419600 dateArray = datetime.datetime.utcfromtimestamp(timeStamp) otherStyleTime = dateArray.strftime("%Y-%m-%d %H:%M:%S") >> "2013-10-10 23:40:00"
{獲取當前時間並轉換爲指定日期格式
}
方法一:
import time 得到當前時間時間戳 now = int(time.time()) ->這是時間戳 轉換爲其餘日期格式,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 得到當前時間 now = datetime.datetime.now() ->這是時間數組格式 轉換爲指定的格式: otherStyleTime = now.strftime("%Y-%m-%d %H:%M:%S")
{得到三天前的時間
}
import time import datetime 先得到時間數組格式的日期 threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3)) 轉換爲時間戳: timeStamp = int(time.mktime(threeDayAgo.timetuple())) 轉換爲其餘字符串格式: otherStyleTime = threeDayAgo.strftime("%Y-%m-%d %H:%M:%S")
注:timedelta()的參數有:days,hours,seconds,microseconds
{給定時間戳,計算該時間的幾天前時間
}
timeStamp = 1381419600 #先轉換爲datetime import datetime import time dateArray = datetime.datetime.utcfromtimestamp(timeStamp) threeDayAgo = dateArray - datetime.timedelta(days = 3)

,能夠轉換爲其餘的任意格式了
