#coding=utf-8import time# 另种时间格式： 1.从Epoch开始记的秒数，类似Unix时间戳 2.9个integer的tuple, structtime# The tuple items are:#   year (four digits, e.g. 1998)#   month (1-12)#   day (1-31)#   hours (0-23)#   minutes (0-59)#   seconds (0-59)#   weekday (0-6, Monday is 0)#   Julian day (day in the year, 1-366)#   DST (Daylight Savings Time) flag (-1, 0 or 1)########################### timestamp与tuple互相转换cur_timestamp = time.time()  # 当前时间。# >>>格式：时间戳,1459001151.0cur_timetuple = time.localtime(cur_timestamp)  # 1: 从时间戳转换为tuple(当地时间)  # 2：不传入参数时，返回当前时间的tuple（当地时间）# >>> time.struct_time(tm_year=2016, tm_mon=3, tm_mday=26, tm_hour=21, tm_min=55, tm_sec=30, tm_wday=5, tm_yday=86, tm_isdst=0)cur_timetuple =  time.gmtime(cur_timestamp)# 1: 从时间戳转换为tuple, UTC (a.k.a. GMT).# 2：不传入参数时，返回当前时间的tuple, UTC (a.k.a.
