How can I configure logging in Python using a config file?

You can configure logging in Python using a config file by utilizing the logging.config module. Would you like a sample configuration?

Yes, please provide a sample configuration.

Here's a basic example of a logging configuration in a JSON file:

{
  "version": 1,
  "disable_existing_loggers": false,
  "formatters": {
    "simple": {
      "format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
    }
  },
  "handlers": {
    "console": {
      "class": "logging.StreamHandler",
      "formatter": "simple"
    }
  },
  "loggers": {
    "my_logger": {
      "level": "DEBUG",
      "handlers": ["console"],
      "propagate": false
    }
  }
}

You can load this configuration using logging.config.fileConfig() or logging.config.dictConfig().

How do I load this configuration in my Python script?

You can load the configuration using the following code:

import logging
import logging.config
import json

with open('logging_config.json', 'r') as f:
    config = json.load(f)
    logging.config.dictConfig(config)

logger = logging.getLogger('my_logger')
logger.debug('This is a debug message.')

Make sure to replace 'logging_config.json' with the path to your config file.
