Is inifinite loop not a good practice?

  1. Alvin A. Delagon enlightened us with:
    I think it's just fine. You could improve it a bit by using something

    class Monitor(Thread):
    def __init__(self, *args, **kwargs):
    Thread.__init__(self, *args, **kwargs)
    self.interrupted = False

    def run(self):
    while not interrupted:

    def interrupt(self):
    self.interrupted = True
    The advantage there is a stability issue. If your program quits,
    you've got a problem. Using crontab, the program is started over and
    over again, so even if it crashes, it'll be restarted in time for the
    next monitor run. Cron has been around for such a long time that the
    chance of a crash is much less than with a freshly developed program.

  2. Greetings,

    I have to write a python script that would continously monitor and
    process a queue database. Once the script sees an unprocessed record it
    will create a thread to process it otherwise it will do nothing. I've
    been planning to do an infinite loop within the script to do this but
    I've been hearing comments that infinite loop is a bad programming
    practice. I'm opted to run the script via crontab but I consider it as
    my last resort. Do you have any suggestions on the design? Thanks in
