How can I create custom logging handlers in Python?

You can create custom logging handlers by subclassing the logging.Handler class. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import logging

class CustomHandler(logging.Handler):
    def emit(self, record):
        log_entry = self.format(record)
        print(f'Custom log: {log_entry}')

logger = logging.getLogger('my_logger')
logger.setLevel(logging.DEBUG)

custom_handler = CustomHandler()
custom_handler.setFormatter(logging.Formatter('%(asctime)s - %(levelname)s - %(message)s'))
logger.addHandler(custom_handler)

logger.debug('This is a debug message.')

What are some use cases for custom logging handlers?

Custom logging handlers can be used for sending logs to external systems, formatting logs differently, or filtering log messages.
