Python timer using sample sharing

Copy CodeThe code is as follows:

Class Sltimer (multiprocessing. Process):
#from datetime Import DateTime
#import time

def __init__ (self, Target=none, args= (), Kwargs={},date=none,time=none):
'''\
@param date 1900-01-01
@param time 00:00:00
'''
Super (Sltimer,self) __init__ (Target=target,args=args,kwargs=kwargs)
_date = ' '
If date is None:
_date = DateTime.Now (). __str__ () [: 10]
else:
_date = Date

_time = ' '
If time is None:
_time = DateTime.Now (). __str__ () [11:19]
Else
_time = time

Self.__runtime = '%s%s '% (_date,_time)

def run (self):
Timelen = Len (' 1900-00-00 00:00:00 ')

While True:
now = DateTime.Now (). __str__ () [: Timelen]
If Now>=self.__runtime:
Break
print ' sleeping ...%s '% now
Time.sleep (1.0)

Super (Sltimer,self). Run ()

Test

Copy the Code code as follows:

Def show1 ():
From datetime import datetime
print ' hello,current time:%s '% DateTime.Now (). __str__ ()

Def t23 ():
From Stock.task import Sltimer

Timer = Sltimer (Show1, time= ' 16:31:50 ')
