I've been in the prototyping stage. I just run = it from the command line and use print() statements to let me know the = thing is making acceptable process. At some point, I need to properly daemonize it. Write an init script, = find a logging framework/module, batton all the hatches down, so to = speak. I=92m curious if there=92s a technique one could use to get half way = there. Basically, with minimal modifications, I=92d like to get it = running at startup. So I can put a line like this in rc.local nohup python3 myMain.py 2>&1 > /var/log/mylog.log & Then I can =93check=94 on it when I need to with a tail -f = /var/log/mylog.log. But then I have the problem of managing the log = size. And also I either have to wait for stdout to flush, or insert = sys.stdout.flush() after any of my print()=92s. I haven=92t done a lot of these daemon processes (and this is my first = with python), so I was curious what those with experience do here.=
