Python logging module is printing lines multiple times

Question

I have the following code:

import logging
class A(object):
    def __init__(self):
        self._l = self._get_logger()

    def _get_logger(self):
        l         


        

Answer 1

Since python 3.2 and newer:

Consider using hasHandlers() to check if a logger has handlers or not.
