How to exit from Python without traceback?
Question: I would like to know how to I exit from Python without having an traceback
dump on the output.

I still want want to be able to return an error code but I do not want to
display the traceback log.

I want to be able to exit using `exit(number)` without trace but in case of an
Exception (not an exit) I want the trace.


Answer: You are presumably encountering an exception and the program is exiting
because of this (with a traceback). The first thing to do therefore is to
catch that exception, before exiting cleanly (maybe with a message, example
given).

Try something like this in your `main` routine:

    
    
    import sys, traceback
    
    def main():
        try:
            do main program stuff here
            ....
        except KeyboardInterrupt:
            print "Shutdown requested...exiting"
        except Exception:
            traceback.print_exc(file=sys.stdout)
        sys.exit(0)
    
    if __name__ == "__main__":
        main()
