Scheduling Python Script to run every hour accurately

Maybe this can help: Advanced Python Scheduler

Here's a small piece of code from their documentation:

from apscheduler.schedulers.blocking import BlockingSchedulerdef some_job():    print "Decorated job"scheduler = BlockingScheduler()scheduler.add_job(some_job, 'interval', hours=1)scheduler.start()

To run something every 10 minutes past the hour.

from datetime import datetime, timedeltawhile 1:    print 'Run something..'    dt = datetime.now() + timedelta(hours=1)    dt = dt.replace(minute=10)    while datetime.now() < dt:        time.sleep(1)

For apscheduler < 3.0, see Unknown's answer.

For apscheduler > 3.0

from apscheduler.schedulers.blocking import BlockingSchedulersched = BlockingScheduler()@sched.scheduled_job('interval', seconds=10)def timed_job():    print('This job is run every 10 seconds.')@sched.scheduled_job('cron', day_of_week='mon-fri', hour=10)def scheduled_job():    print('This job is run every weekday at 10am.')sched.configure(options_from_ini_file)sched.start()

Update:

apscheduler documentation.

This for apscheduler-3.3.1 on Python 3.6.2.
