You haven't given us the code for your MyLogger class, so it's difficult
to say exactly what the problem is.

However, I have a guess.  Does MyLogger.set_logger() contain a call to
addHandler()?  Each call to addHandler() adds another handler to your
logger, and when you call log.critical() [or any other log function] you
get one line of output for each handler.

You should only call addHandler() once.
