1.str转时间戳
# 字符类型的时间 tss1 = ‘2013-10-10 23:40:00‘ # 转为时间数组 timeArray = time.strptime(tss1, "%Y-%m-%d %H:%M:%S") print timeArray # timeArray可以调用tm_year等 print timeArray.tm_year # 2013 # 转为时间戳 timeStamp = int(time.mktime(timeArray)) print timeStamp # 1381419600 # 结果如下 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
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") # 转为其它显示格式 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
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 15:40:00
4.获取当前时间并且用指定格式显示
# time获取当前时间戳 now = int(time.time()) # 1533952277 timeArray = time.localtime(now) print timeArray otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray) print otherStyleTime # 结果如下 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获取当前时间，数组格式 now = datetime.datetime.now() print now otherStyleTime = now.strftime("%Y--%m--%d %H:%M:%S") print otherStyleTime # 结果如下： 2018-08-11 09:51:17.362986 2018--08--11 09:51:17
