Indeed, THERE IS a removeHandler() method. In the documentation of python 2.6, it is mentioned in '16.6.5. Logger Objects', directly after the addHandler() method. If you found the addHandler() method there, you should have found removeHandler() too. And a simple >>> dir(log) ['__doc__', '__init__', '__module__', '_log', 'addFilter', 'addHandler', 'callHandlers', 'critical', 'debug', 'disabled', 'error', 'exception', 'fatal', 'filter', 'filters', 'findCaller', 'getEffectiveLevel', 'handle', 'handlers', 'info', 'isEnabledFor', 'level', 'log', 'makeRecord', 'manager', 'name', 'parent', 'propagate', 'removeFilter', 'removeHandler', 'root', 'setLevel', 'warn', 'warning'] also would have revealed it to you. >I can hack it by doing > > log = logging.getLogger() # get the root logger > del log.handlers[:] # reach inside and nuke 'em > log.addHandler(...) # install the one(s) I want > >but it feels a little dirty to reach into logging.root.handlers since >there are other methods for adding/removing handlers.

What about this: >>> for handler in log.handlers: ... log.removeHandler(handler) I think, that's just one of the tasks that removeHandler() was written for. >Is there a better way to do this, or do I just suck it up and deal >with the (potentially thread-ignorant, as it doesn't lock) hack? One of the best ways would be to read the documentation. And to do some exploration, e.g. by means of dir() and help(), could also be quite instructive. This experience cannot be replaced by documentation-research requests to the Usenet. Best regards, Gunther -- https://mail.python.org/mailman/listinfo/python-list
