What are Python logging handlers and how do I use them?

Python logging handlers are components that send log messages to different destinations. They allow you to configure how and where your logs are outputted.

Can you give me an example of a logging handler?

Sure! A common logging handler is the StreamHandler, which sends log messages to the console. You can use it like this:

import logging

logger = logging.getLogger('my_logger')
handler = logging.StreamHandler()
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
logger.debug('This is a debug message')

What other types of logging handlers are available?

There are several types of logging handlers, including:

• FileHandler: Writes log messages to a file.
• SMTPHandler: Sends log messages via email.
• HTTPHandler: Sends log messages to a web server.

How can I configure multiple handlers?

You can add multiple handlers to the same logger. For example, you can log to both the console and a file:

file_handler = logging.FileHandler('my_log.log')
logger.addHandler(file_handler)
