... logging: level



Notes

We've made a small change to the log.py file.

logger.py

Important: do not name this file logging.py.

import logging

logger = logging.getLogger(__name__)

# the handler determines where the logs go: stdout/file
handler = logging.StreamHandler()

# the formatter determines what our logs will look like
fmt = '%(levelname)s %(asctime)s [%(filename)s:%(funcName)s:%(lineno)d] %(message)s'
formatter = logging.Formatter(fmt)
handler.setFormatter(formatter)

logger.addHandler(handler)
# you can change this line to see different lines being logged
logger.setLevel(logging.WARNING)

logger.debug('this is a debug statement')
logger.info('this is a info statement')
logger.warning('this is a warning statement')
logger.critical('this is a critical statement')
logger.error('this is a error statement')

One thing to remember is that there is an order to the loglevels. If the loglevel is set to INFO then it will show all the INFO-level logs as well as all the logs that are more critical (WARNING, CRITICAL and ERROR). If you want to show everything then it's best to set the level to DEBUG.
