在编写代码时,往往涉及时间、日期、时间戳的相互转换。
2. 示例
# 引入模块
import time, datetime2.1 str类型的日期转换为时间戳
tss1 = '2013-10-10 23:40:00' tm = time.strptime(tss1, '%Y-%m-%d %H:%M:%S') # 转为时间数组 timeArray = time.strptime(tss1, "%Y-%m-%d %H:%M:%S") # timeArray可以调用tm_year等 print timeArray # 转为时间戳 timeStamp = int(time.mktime(timeArray)) print timeStamp # 13814196002.2 更改str类型日期的显示格式
tss2 = "2013-10-10 23:40:00" # 转为数组 timeArray = time.strptime(tss2, "%Y-%m-%d %H:%M:%S") # 转为其它格式 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 23:40:002.3 时间戳转换为指定格式的日期
# 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 15:40:002.4 获取当前时间并且用指定格式显示
# 获取当前时间戳 now = int(time.time()) timeArray = time.localtime(now) otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray) print otherStyleTime # 2017--12--11 19:18:02 # 获取当前时间,数组格式 now = datetime.datetime.now() otherStyleTime = now.strftime("%Y--%m--%d %H:%M:%S") print otherStyleTime # 2017--12--11 19:18:02转自: 大神的博客
