Python - Quick Start of Logging

import logging

logger = logging.getLogger(__name__) # this will show current module in the log line
logger.setLevel(logging.INFO)

# create a file handler

handler = logging.FileHandler('hello.log')
handler.setLevel(logging.INFO)

# create a logging format

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)

# add the handlers to the logger

logger.addHandler(handler)

logger.info('Happy logging!')

try:
    open('/path/to/does/not/exist', 'rb')
except (SystemExit, KeyboardInterrupt):
    raise
except Exception, e:
    logger.error('Failed to open file', exc_info=True)
