Ref: [1] - Good logging practice in Python
A very simple file logger:
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!')
Logging in a catch
try:
open('/path/to/does/not/exist', 'rb')
except (SystemExit, KeyboardInterrupt):
raise
except Exception, e:
logger.error('Failed to open file', exc_info=True)
