python中time、date、時間戳的轉換

python中時間、日期、時間戳的轉換

import time, datetime

str類型的日期轉換爲時間戳

# 字符類型的時間
tss1 = '2013-10-10 23:40:00'
# 轉爲時間數組
timeArray = time.strptime(tss1, "%Y-%m-%d %H:%M:%S")
print timeArray     
# timeArray能夠調用tm_year等
print timeArray.tm_year   # 2013
# 轉爲時間戳
timeStamp = int(time.mktime(timeArray))
print timeStamp  # 1381419600


# 結果以下
time.struct_time(tm_year=2013, tm_mon=10, tm_mday=10, tm_hour=23, tm_min=40, tm_sec=0, tm_wday=3, tm_yday=283, tm_isdst=-1)
2013
1381419600

更改str類型日期的顯示格式

 

tss2 = "2013-10-10 23:40:00"
# 轉爲數組
timeArray = time.strptime(tss2, "%Y-%m-%d %H:%M:%S")
# 轉爲其它顯示格式
otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray)
print otherStyleTime  # 2013/10/10 23:40:00

tss3 = "2013/10/10 23:40:00"
timeArray = time.strptime(tss3, "%Y/%m/%d %H:%M:%S")
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print otherStyleTime  # 2013-10-10 23:40:00

 

時間戳轉換爲指定格式的日期

# 使用time
timeStamp = 1381419600
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray)
print otherStyleTime   # 2013--10--10 23:40:00
# 使用datetime
timeStamp = 1381419600
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
otherStyleTime = dateArray.strftime("%Y--%m--%d %H:%M:%S")
print otherStyleTime   # 2013--10--10 15:40:00　

獲取當前時間而且用指定格式顯示

# time獲取當前時間戳
now = int(time.time())     # 1533952277
timeArray = time.localtime(now)
print timeArray
otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray)
print otherStyleTime    

# 結果以下
time.struct_time(tm_year=2018, tm_mon=8, tm_mday=11, tm_hour=9, tm_min=51, tm_sec=17, tm_wday=5, tm_yday=223, tm_isdst=0)
2018--08--11 09:51:17


# datetime獲取當前時間，數組格式
now = datetime.datetime.now()
print now
otherStyleTime = now.strftime("%Y--%m--%d %H:%M:%S")
print otherStyleTime  

# 結果以下：
2018-08-11 09:51:17.362986
2018--08--11 09:51:17
