Nothing to do with python - its the way logging is designed, and it makes
sense: if at one place you attach the logger named foo.bar to a handler,
and at another place obtain a reference to foo.bar to log some stuff, you
don't want to reiterate the whole handler-attaching stuff.

So you simply abused the logging module - just set up the logger once, and
then obtain a reference to it using logging.getLogger whenever you need it
- that totally rids you of your logger class, that so far doesn't do much
anyway. Like this:

------
logger = logging.getLogger(name)
logger.propagate = False
handler = logging.FileHandler(dir + '/' + name + '.log')
logger.addHandler(handler)

class Test:

    def test_me(self):
        logger = logging.getLogger(name)
        logger.debug("test_me")

------
