You are missing the worker thread part in main. It is neccessary because this thread will call your functions. Right now there is no such thread in your app.

What are you trying to do? Do you want to have a flask API that can schedule jobs on command? For that you could add something like this:

def some_job():
    print("This job was scheduled from flask")

@app.route('/schedule/every/<int:count>/<period>')
def add_to_schedule(count=1, period=None):
    job = schedule.every(count)
    if count == 1:
        if period == 'day':
            job = job.day
        elif period == 'hour':
            job = job.hour
        elif period == 'minute':
            job = job.minute
        elif period == 'second':
            job = job.second
        else:
            return "Invalid period " + period
    else:
        if period == 'day':
            job = job.days
        elif period == 'hour':
            job = job.hours
        elif period == 'minute':
            job = job.minutes
        elif period == 'second':
            job = job.seconds
        else:
            return "Invalid period " + period
    job.do(some_job)
    return "OK"

And you could add more parameters and whatnot as necessary. Hope this helps!
