Pythonタイマー使用例の共有

复制代码代码如下:

class SLTimer(multiprocessing.Process):
#from datetime import datetime
#インポート時間

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日付はなし:
_date = datetime.now().__str__()[:10]
else :
_date = date

_time = ''
time が None の場合:
_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 '眠っています... %s ' % now
time.sleep(1.0)

super(SLTimer,self).run()

测试

复制代码代码如下:

def show1():
from datetime import datetime
print 'hello ,現在時刻:%s' % datetime.now().__str__()

def t23():
from stock.task import SLTimer

timer = SLTimer(show1, time='16:31:50')
timer.start()
