class T:
def __init__(self, taskid):
self.times = 10 #<--------------the largest number of this task will be executed
self.now = dt.now()
self.every = td(seconds=4) #<------frequency of task being polled
self.taskid = taskid
def __call__(self): #<--------------content of task
print self.taskid, ":", dt.now()-self.now
self.now =dt.now()
def schedule(self): #<--------------task'schedule：
return dt.now()+td(seconds=2) #return bool() or datetime.datetime(...)[means the time to run task]
task1 = T(1)
task2 = T(2)
#set task2's schedule
task2.schedule = lambda: True if os.environ['LOGNAME']=='root' else False
app = App()
app.add(task1)
app.add(task2
app.run()
