Logging module not writing to file

Question

I'm using logging module, and I've passed in the same parameters that I have on other jobs that are currently working:

import logging
from inst_config import config3

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s [%(levelname)s] - %(message)s',
    filename=config3.GET_LOGFILE(config3.REQUESTS_USAGE_LOGFILE))
logging.warning('This should go in the file.')

if __name__ == '__main__':
    logging.info('Starting unload.')

Using this method to create the filename:

REQUESTS_USAGE_LOGFILE = r'C:\RunLogs\Requests_Usage\requests_usage_runlog_{}.txt'.format(
        CUR_MONTH)
def GET_LOGFILE(logfile):
    """Truncates file and returns."""
    with open(logfile, 'w'):
        pass
    return logfile

When I run it, however, it is creating the file, and then still outputting the logging info to the console. I'm running in Powershell.

Just tried putting it inside the main statement like this:

if __name__ == '__main__':
    logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s [%(levelname)s] - %(message)s',
    filename=config3.GET_LOGFILE(config3.REQUESTS_USAGE_LOGFILE))

    logging.warning('This should go in the file.')

Still no luck.

Answer 1

I add the following lines before the logging.basicConfig() and it worked for me.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)
