1.将字符串的时间转换为时间戳
方法:
| 1 2 3 4 5 6 7 | a = "2013-10-10 23:40:00" #将其转换为时间数组 import time timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S" ) #转换为时间戳: timeStamp = int (time.mktime(timeArray)) timeStamp = = 1381419600 |
如a = "2013-10-10 23:40:00",想改为 a = "2013/10/10 23:40:00" 方法:先转换为时间数组,然后转换为其他格式
| 1 2 | timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S" ) otherStyleTime = time.strftime( "%Y/%m/%d %H:%M:%S" , timeArray) |
方法一: 利用localtime()转换为时间数组,然后格式化为需要的格式,如
| 1 2 3 4 | timeStamp = 1381419600 timeArray = time.localtime(timeStamp) otherStyleTime = time.strftime( "%Y-%m-%d %H:%M:%S" , timeArray) otherStyletime = = "2013-10-10 23:40:00" |
方法二:
| 1 2 3 4 5 | import datetime timeStamp = 1381419600 dateArray = datetime.datetime.utcfromtimestamp(timeStamp) otherStyleTime = dateArray.strftime( "%Y-%m-%d %H:%M:%S" ) otherStyletime = = "2013-10-10 23:40:00" |
方法一:
| 1 2 3 4 5 6 | import time #获得当前时间时间戳 now = int (time.time()) - >这是时间戳 #转换为其他日期格式,如:"%Y-%m-%d %H:%M:%S" timeArray = time.localtime(timeStamp) otherStyleTime = time.strftime( "%Y-%m-%d %H:%M:%S" , timeArray) |
方法二:
| 1 2 3 4 5 | import datetime #获得当前时间 now = datetime.datetime.now() - >这是时间数组格式 #转换为指定的格式: otherStyleTime = now.strftime( "%Y-%m-%d %H:%M:%S" ) |
方法:
| 1 2 3 4 5 6 7 8 9 | import time import datetime #先获得时间数组格式的日期 threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3 )) #转换为时间戳: timeStamp = int (time.mktime(threeDayAgo.timetuple())) #转换为其他字符串格式: otherStyleTime = threeDayAgo.strftime( "%Y-%m-%d %H:%M:%S" ) #注:timedelta()的参数有:days,hours,seconds,microseconds |
| 1 2 3 4 5 6 | timeStamp = 1381419600 #先转换为datetime import datetime import time dateArray = datetime.datetime.utcfromtimestamp(timeStamp) threeDayAgo = dateArray - datetime.timedelta(days = 3 ) |
参考5,可以转换为其他的任意格式了。
