This is probably a gross hack, but then I think one could argue that the one-time "No handlers could be found for" warning is a misfeature -- at least without a clean way to suppress it. I don't know the history of that warning though: -------------- mylib.py ----------------------- import logging log = logging.getLogger("mylib") def func(): log.warn("don't go near the river") log.error("I'm drowning!") -------------------------------------------------- -------------- myscript.py ----------------------- import sys import logging import mylib if __name__ == "__main__": if "-v" in sys.argv: logging.basicConfig() else: logging.Logger.manager.emittedNoHandlerWarning = True mylib.func() -------------------------------------------------- $ python myscript.py $ python myscript.py -v WARNING:mylib:don't go near the river ERROR:mylib:I'm drowning! hackily yours, Trent -- Trent Mick [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
