[Python] Python proper logging with filehandlers

I am using python logging in my django application. A class that connects to a backend api initialises this logger with a filehandler if needed. The class gets instantiated everytime an api call is made. I have tried making sure additional handlers are not added every time, but

lsof | grep my.log


shows an increasing amount of handlers on my log file and after a while my server fails due to this open file limit.

self.logger = logging.getLogger("FPA")

try:
if self.logger.handlers[0].__class__.__name__=="FileHandler":
pass
except Exception, e:
print 'new filehandler added'+str(e)
ch = logging.FileHandler(FPA_LOG_TARGET)
formatter = logging.Formatter("%(asctime)s - %(levelname)s - %(message)s - %(pathname)s @ line %(lineno)d")
ch.setFormatter(formatter)
self.logger.setLevel(logging.DEBUG)
self.logger.addHandler(ch)


I realise this may not be the best way to do this, but I have not found the error in my implementation so far.
