Avoid check if logger exists

Question

When using logging in python like this

import logging
logging.basicConfig(level=logging.INFO)
logger = None
if <some condition>:
   logger = logging.getLogger(__name__)
... some code ...
logger.debug('message')

is it possible to avoid calling logger.debug if it does not exist without if statement?

Answer 1

That's not how you use logging: it's missing the point entirely. The point is to always just log, and then (at the app level) configure handlers appropriately so that they either record the debug level or not. Your app-level configuration can even set the handler for loggers in each module. See the Python logging docs for more info.
