How do I use logging handlers in Python's logging module?

In Python's logging module, logging handlers are used to send log messages to different destinations. You can use handlers like StreamHandler, FileHandler, and more.

Can you give me an example of using a FileHandler?

Sure! Here's a simple example:

import logging

# Create a logger
logger = logging.getLogger('my_logger')
logger.setLevel(logging.DEBUG)

# Create a FileHandler
file_handler = logging.FileHandler('my_log.log')
file_handler.setLevel(logging.DEBUG)

# Create a formatter and set it for the handler
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_handler.setFormatter(formatter)

# Add the handler to the logger
logger.addHandler(file_handler)

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

What other handlers can I use?

You can use several other handlers like StreamHandler for console output, SMTPHandler for sending logs via email, and RotatingFileHandler for log rotation.
