Hi Sanjeet,
what I usually do is, I create a "task.py" file in my project's package,
where I put all the functions that should be run periodically or on
application startup. I also add a function called "add_tasks" to it,
that is run at application start-up and adds all functions to the
scheduler. If you want, you can also add another function, called e.g.
"run_startup_tasks" that runs all tasks that should be run, when your
app starts.
HTH, Chris
