Missing logging output in Python

[W. Matthew Wilson]

I made that code into a program like this:

### BEGIN

import logging

def configure_logging():

    logging.basicConfig(level=logging.DEBUG, format='%(asctime)s
%(name)-12s %(levelname)8s %(message)s',
                        datefmt='%Y-%m-%d\t%H:%M:%s',
                        filename='/tmp/logfun.log', filemode='a')

    # define a Handler that writes INFO messages to sys.stderr
    console = logging.StreamHandler()
    console.setLevel(logging.INFO)

    # set format that is cleaber for console use
    formatter = logging.Formatter('%(name)-12s: %(levelname)-8s
%(message)s')

    # tell the handler to use this format
    console.setFormatter(formatter)

    # add the handler to the root logger
    logging.getLogger('').addHandler(console)

if __name__ == '__main__':

    configure_logging()

    logging.debug('a')
    logging.info('b')
    logging.warn('c')
    logging.error('d')
    logging.critical('e')

### END

and when I run the program, I get INFO and greater messages to stderr:

$ python logfun.py
root        : INFO     b
root        : WARNING  c
root        : ERROR    d
root        : CRITICAL e

and I get this stuff in the log file:

$ cat /tmp/logfun.log
2013-03-12 07:31:1363087862 root            DEBUG a
2013-03-12 07:31:1363087862 root             INFO b
2013-03-12 07:31:1363087862 root          WARNING c
2013-03-12 07:31:1363087862 root            ERROR d
2013-03-12 07:31:1363087862 root         CRITICAL e

In other words, your code works!  Maybe you should check permissions on the
file you are writing to.
