在 jobstore (apscheduler) 中找不到 Python 高级调度程序作业

Question

考虑这段小代码

from apscheduler.scheduler import Scheduler
import time

class First():
    def __init__(self):
        self.remove_job=None
    def go(self):
        self.remove_job('test')
class Sched():
    def __init__(self):
        self.sched = Scheduler()
        self.sched.add_interval_job(    self.execute,
                        seconds=1,
                        name = 'test'
                        )
    def execute(self):
        print "i'm alive"
    def remove_job(self,job):
        self.sched.print_jobs()
        self.sched.unschedule_job(job)

def main():
    first = First()
    sched = Sched()
    first.remove_job=sched.remove_job
    sched.sched.start()
    time.sleep(5)
    first.go()
    return 0

if __name__ == '__main__':
    main()

python sched_test.py 
i'm alive
i'm alive
i'm alive
i'm alive
i'm alive
Jobstore default:
    test (trigger: interval[0:00:01], next run at: 2011-12-22 01:25:36.577572)
Traceback (most recent call last):
  File "sched_test.py", line 55, in <module>
    main()
  File "sched_test.py", line 51, in main
    first.go()
  File "sched_test.py", line 31, in go
    self.remove_job('test')
  File "sched_test.py", line 43, in remove_job
    self.sched.unschedule_job(job)
  File "/usr/local/lib/python2.7/dist-packages/APScheduler-2.0.2-py2.7.egg/apscheduler/scheduler.py", line 401, in unschedule_job
    raise KeyError('Job "%s" is not scheduled in any job store' % job)
KeyError: 'Job "test" is not scheduled in any job store'

为什么在打印作业作品时出现此错误？print_jobs() 给了我正确的概述。

有人可以阐明这个问题吗？

这对大多数人来说可能是显而易见的，但我花了一段时间才明白。只想分享是什么让我的代码工作:

myJobName= "Homework"

for job in self.sched.get_jobs():
    if job.name == "Homework":
        self.sched.unschedule_job(job)
        print "No more homework!"
