Python: logging: Logging Exceptions

Logger.exception() method is used to log exceptions. It logs a message with level ERROR on this logger and dumps a stack trace along with it. This method should only be called from an exception handler.

import logging

logger = logging.getLogger(__name__)
logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s')

def processData():
    try:
        logger.info("Processing data")
        10/0
    except ZeroDivisionError as inst:
        logger.exception(inst)

processData()

Run above program, you will get following output.
