In general for Python 2.x, the code
import logging
logging.getLogger('foo').warning('test')
will produce
No handlers could be found for logger "foo"
unless loggers have been configured, e.g. by calling logging.warning()
- that call implicitly adds a console handler to the root logger, if
no other handlers have been configured for the root logger.
In Python 3.2 and later, if no handlers have been configured, messages
at level WARNING and greater will be printed to sys.stderr using a
"handler of last resort" - see
