How to export a logging level?

[Vincent Vande Vyvre]

In my application I import a module and I want to set the same logging
level
as the main app to this module.

I've tried this code

main.py

import logging
logger = logging.getLogger(__name__)
lvl = logging.DEBUG
LOG_FORMAT = "%(asctime)-6s %(levelname)s: %(name)s - %(message)s"
logging.basicConfig(format=LOG_FORMAT, datefmt='%H:%M:%S', level=lvl)

from mymodule.myfile import MyClass

....
def load_myclass(self):
lvl = logger.getEffectiveLevel()
mc = MyClass(self, lvl)


myfile.py

import logging
logger = logging.getLogger(__name__)

class MyClass(object):
def __init__(self, main, lvl):
logger.setLevel(lvl)

If I set the level to logging.DEBUG I can see all infos from the main
but anything
from my module.

Thanks for your advice.
