This article mainly introduces the relevant knowledge of "how to realize the APScheduler timing task of the python package". The editor shows you the operation process through the actual case, the operation method is simple and fast, and the practicality is strong. I hope this article "how to realize the APScheduler timing task of the python package" can help you solve the problem.

1. Install pip install apscheduler 2. Execute it regularly.

Create a new scheduler scheduler

Add a job store scheduling task

Run scheduling task

Import datetimefrom apscheduler.schedulers.blocking import BlockingSchedulerdef task (name): print (% s tells you the time is:% s. Format (name, datetime.datetime.now ()) # the task will be executed once at 13:14:52 on 2022-05-20 scheduler = BlockingScheduler () scheduler.add_job (task, 'date', run_date=datetime.datetime (2022, 5, 20, 13, 14, 52), args= [' autofelix'], id='task') scheduler.start () III.

When you schedule a job, you need to select a trigger for the job to describe when the job is triggered

Date specifies a date at one time

How often does interval execute within a certain time range?

From apscheduler.schedulers.blocking import BlockingSchedulerdef task (): print ('I am Brother Flying Rabbit') # execute scheduler = BlockingScheduler () scheduler.add_job (task, 'interval', seconds=10, id='task') scheduler.start () every 10 seconds.

Cron and Linux crontab formats are compatible and the most powerful

From apscheduler.schedulers.blocking import BlockingSchedulerf = open ('status.text',' asides, encoding='utf8') sc = BlockingScheduler () @ sc.scheduled_job ('cron', day_of_week='*', hour=1, minute='30') Second='50') if name ='_ _ main__':try:sc.start () f.write ('scheduled task successfully executed') except Exception as e:sc.shutdown () f.write ('scheduled task execution failed') finally:f.close () 5. Execute every few minutes

/ 2: executed every 2 minutes

/ 1: executed every 1 minute

From apscheduler.schedulers.blocking import BlockingSchedulerdef task (): print ('your task is executed every 2 minutes') scheduler = BlockingScheduler () scheduler.add_job (job1, 'cron', minute= "/ 2", id='task') scheduler.start () 6. Execute every hour

Jitter: represents the number of seconds that can float up and down

From apscheduler.schedulers.blocking import BlockingSchedulerdef task (): print ('your task is executed every hour') scheduler = BlockingScheduler () scheduler.add_job (task, 'interval', hours=1, id='task') # scheduler.add_job (task,' interval', hours=1, id='task', jitter=120) scheduler.start () 7. Scheduler category

BlockingScheduler: when the scheduler is the only thing to run in your application

BackgroundScheduler: use it when you are not running any other framework and want the scheduler to execute in the background of your application (even if the charging pile is in this way)

AsyncIOScheduler: use it when your program uses asyncio (an asynchronous framework)

GeventScheduler: use it when your program uses gevent (the high-performance Python concurrency framework)

TornadoScheduler: use it when your program is based on Tornado (a web framework)

TwistedScheduler: use it when your program uses Twisted (an asynchronous framework)

QtScheduler: if your application is a Qt application, you can use it
