 #python time 模块

 import time

 print(time.time())#返回当前的时间

 print(time.ctime(time.time()-8600))

 trs=time.gmtime()#可以拆开里面的值



 print(trs.tm_year,trs.tm_mon)



 print("{year}-{month}".format(year=trs.tm_year,month=trs.tm_mon))

 print(time.localtime(time.time()))



 print(time.mktime(trs))#可以把一个时间对象转变成一个时间戳



 print(time.strftime("%Y_%m_%d %H_%M_%S",time.localtime()))#转化成当前时间,把时间对象转化成字符串

 #转化成格林威治的时间是time.gtime()

 r=time.strptime("2016-05-16","%Y-%m-%d")

 print(r)#转化成时间对象

 print(time.mktime(r))#将时间对象转化为时间戳





 #datetime模块，

 import time,datetime

 p=datetime.date.today()

 print(datetime.date.today(),type(p))

 print(datetime.datetime.now())

 current=datetime.datetime.now()

 print(current.timetuple())#返回struct_time格式



 print(datetime.datetime.now()+datetime.timedelta(days=10))#往后延长十天

 ss=current.replace(2015,9,14)

 #回到之前某一年某一月某一日

 print(current>ss)#比较时间大小的

 print(datetime.datetime.strptime("21/11/06 16:30","%d/%m/%y %H:%M"))
