本文實(shí)例為大家分享了Python時(shí)間戳使用和相互轉(zhuǎn)換的具體代碼，供大家參考，具體內(nèi)容如下
1.將字符串的時(shí)間轉(zhuǎn)換為時(shí)間戳
方法:

import time a = "2013-10-10 23:40:00" # 將其轉(zhuǎn)換為時(shí)間數(shù)組 timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S") # 轉(zhuǎn)換為時(shí)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(shí)間數(shù)組,然后轉(zhuǎn)換為其他格式
|

2
3
|
import time timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S") otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray) |
3.時(shí)間戳轉(zhuǎn)換為指定格式日期:
方法一:
利用localtime()轉(zhuǎn)換為時(shí)間數(shù)組,然后格式化為需要的格式,如
|
1
2
3
4
5
6
|
import time 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:
|
1
2
3
4
5
|
import datetime timeStamp = 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(shí)間并轉(zhuǎn)換為指定日期格式
方法一:
|
1
2
3
4
5
6
7
8
|
import time # 獲得當(dāng)前時(shí)間時(shí)間戳 now = int(time.time()) # 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：
|
1
2
3
4
5
6
7
|
import datetime #獲得當(dāng)前時(shí)間 now = datetime.datetime.now() #這是時(shí)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(shí)間
方法:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
import time import datetime # 先獲得時(shí)間數(shù)組格式的日期 threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3)) # 轉(zhuǎn)換為時(shí)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,microseconds |
6.給定時(shí)間戳,計(jì)算該時(shí)間的幾天前時(shí)間:
|
1
2
3
4
5
6
7
8
9
|
timeStamp = 1381419600 # 先轉(zhuǎn)換為datetime import datetime import time dateArray = 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 |
