How to schedule a function to run every hour on Flask?

I have a Flask web hosting with no access to cron command. How can I execute some Python function every hour?
You can use BackgroundScheduler() from APScheduler package (v3.5.3): import time import atexit from apscheduler.schedulers.background import BackgroundScheduler def print_date_time(): print(time.strftime("%A, %d. %B %Y %I:%M:%S %p")) scheduler = BackgroundScheduler() scheduler.add_job(func=print_date_time, trigger="interval", seconds=60) scheduler.start() # Shut down the scheduler when exiting the app atexit.register(lambda: scheduler.shutdown()) Note that two of these schedulers will be launched when Flask is in debug mode.
