I've got a code pattern I use a lot. In each module, I create a logger

logger = logging.getLogger('my.module.name')
class Foo:
def function(self):
logger.debug('stuff')
logger.debug('other stuff')
and so on. This works, but every once in a while I decide that a
particular function needs a more specific logger, so I can adjust the
logging level for that function independent of the rest of the module.
What I really want to do is:
def function(self):
logger = logger.getChild('function')
logger.debug('stuff')
logger.debug('other stuff')
which lets me not have to change any lines of code other than inserting
the one to redefine logger. Unfortunately, that's not legal Python (it
leads to "UnboundLocalError: local variable 'logger' referenced before
assignment").
Any ideas on the best way to implement this?
How about two global references:
globallogger = logger = logging.getLogger('my.module.name')
def function(self):
logger = globallogger.getChild('function')
logger.debug('stuff')
logger.debug('other stuff')
