(1) By calling add_job() see codes 1 to 3 above (2) through the decorator scheduled_job() The first is the most common methodThe second method is primarily to conveniently declare tasks that will not change when the application is runningThe add_job() method returns an apschedulerjobJob instance that you can use to modify or delete the task laterJobmodify(max_instances=6, name='Alternate name') If you want to reschedule the job – that is, change its trigger, you can use either apschedulerjobJobreschedule () or reschedule_job () These methods construct a new trigger for the job and recalculate its next run time based on the new trigger Example Advanced Python Scheduler (APScheduler) is a Python library that lets you schedule your Python code to be executed later, either just once or periodically You can add new jobs or remove old ones on the fly as you please If you store your jobs in a database, they will also survive scheduler restarts and maintain their state

I'm a little bit new with the concept of application schedulers, but what I found here for APScheduler v331, it's something a little bit differentI believe that for the newest versions, the package structure, class names, etc, have changed, so I'm putting here a fresh solution which I made recently, integrated with a basic Flask applicationBackgroundScheduler is a scheduler provided by APScheduler that runs in the background as a separate thread Below is an example of a background scheduler import time from datetime import datetime from apschedulerschedulersbackground import BackgroundScheduler sched = BackgroundScheduler() def tick() print('Tick! I am trying to use package apscheduler 310 to run a python job every day at the same time But it seems do not run the job correctly But it seems do not run the job correctly In the following simple case, the trigger "interval" can work, but "cron" won't

Describe the bug Using python v366, apscheduler v363 BackgroundScheduler and persistent storage Trying to shutdown the BackgroundScheduler without waiting for the running jobs to complete Added "wait=False" but main() doesn't exit Slightly modified the documentation example as below and it shows a similar behavior To Reproduce If you are looking for a quick but scalable way to get a scheduling service up and running for a task, APScheduler might just be the trickThis is the most powerful of the builtin triggers in APScheduler You can specify a variety of different expressions on each field, and when determining the next execution time, it finds the earliest possible time that satisfies the conditions in every field This behavior resembles the "Cron" utility found in most UNIXlike operating systems
