python datetime seconds和时间元组格式转换

python 输出时间格式转换：

datetime： 输出格式为 class

如：datetime.datetime.now()

1. time class转换为time tuple类型

使用timetuple()

time = datetime.datetime.now()

time1 = time.timetuple()

2. timetuple转换为seconds格式

使用time模块的方法mktime()

time2 = time.mktime(time1)

下图为time模块的几种格式的转换方法:
