Determining if root logger is set to DEBUG level in Python?

Question

If I set the logging module to DEBUG with a command line parameter like this:

if (opt["log"] == "debug"):   logging.basicConfig(level=logging.DEBUG) 

How can I later tell if the logger was set to DEBUG? I'm writing a decorator that will time a function if True flag is passed to it, and if no flag is given, it defaults to printing timing information when the root logger is set to DEBUG.

Actually, there's one better: use the code logging.getLogger().isEnabledFor(logging.DEBUG). I found it while trying to understand what to do with the result of getEffectiveLevel().

Below is the code that the logging module itself uses.

def getEffectiveLevel(self):     """     Get the effective level for this logger.      Loop through this logger and its parents in the blogger hierarchy,     looking for a non-zero logging level. Return the first one found.      """     logger = self     while logger:         if logger.level:             return logger.level         logger = logger.parent     return NOTSET  def isEnabledFor(self, level):     """     Is this logger enabled for level ‘level’?     """     if self.manager.disable >= level:         return 0     return level >= self.getEffectiveLevel()
