all Python 3loggingfunction

logging.getLogger()

configuration

Returns a named logger. Loggers form a hierarchy along the dots in their names. Best created at module level: getLogger(__name__).

Syntax

logger = logging.getLogger(name)

The same name always hands back the same object, so you can fetch a logger anywhere instead of threading it through arguments. A record travels up the dotted name hierarchy and the ancestors' handlers fire as well — the usual reason lines appear twice after attaching a handler to both a module logger and the root. A logger's own level defaults to NOTSET, meaning it quietly inherits the level of the nearest ancestor that has one.

Examples

import logging
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
logger.info('сообщение из модуля')

import logging
# иерархия
parent = logging.getLogger('app')
child  = logging.getLogger('app.db')  # наследует настройки parent
