What is the process for utilizing logging in conjunction with Python's fileConfig and setting the filename for the logfile?

The process for utilizing logging in conjunction with Python's fileConfig and setting the filename for the logfile involves the following steps:

1. First, you need to import the logging module and load the logging configuration from a file using the fileConfig method.

import logging.config

logging.config.fileConfig('logging_config.ini')

1. Next, you need to define a logger object in your Python code.

logger = logging.getLogger('my_logger')

1. Finally, you can use the logger to write log messages to a file by specifying the filename in the logging configuration file.

For example, if you have the following logging configuration file called logging_config.ini:

[loggers]
keys=root

[handlers]
keys=consoleHandler,fileHandler

[formatters]
keys=sampleFormatter

[logger_root]
level=DEBUG
handlers=consoleHandler,fileHandler

[handler_consoleHandler]
class=StreamHandler
level=DEBUG
formatter=sampleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=DEBUG
formatter=sampleFormatter
args=('example.log',)

[formatter_sampleFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
datefmt=%Y-%m-%d %H:%M:%S

You can set the filename for the logfile to example.log by specifying it in the args parameter of the handler_fileHandler section.

Then, you can use the logger object to write log messages to the file:

logger.debug('Debug message')
logger.info('Info message')
logger.warning('Warning message')
logger.error('Error message')
logger.critical('Critical message')
