How to write to a file, using the logging Python module?

by

An example of using logging.basicConfig rather than logging.fileHandler()

logging.basicConfig(filename=logname,
                    filemode="a",
                    format="%(asctime)s,%(msecs)d %(name)s %(levelname)s %(message)s",
                    datefmt="%H:%M:%S",
                    level=logging.DEBUG)

logging.info("Running Urban Planning")

logger = logging.getLogger('urbanGUI')

In order, the five parts do the following:

  1. set the output file (filename=logname)
  2. set it to append rather than overwrite (filemode="a")
  3. determine the format of the output message (format=...)
  4. determine the format of the output time (datefmt="%H:%M:%S")
  5. and determine the minimum message level it will accept (level=logging.DEBUG).
