What are logging handlers in Python?

Logging handlers in Python are components that send log messages to their final destination, such as files, streams, or remote servers.

Can you give me an example of how to use a file handler?

Sure! You can use logging.FileHandler to write log messages to a file. Here's a simple example:

import logging

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

# Create a file handler
file_handler = logging.FileHandler('my_log.log')
logger.addHandler(file_handler)

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

What are the different types of logging handlers available?

Python's logging module provides several handlers, including StreamHandler, FileHandler, HTTPHandler, and SMTPHandler, among others.

How can I customize the log format?

You can customize the log format by using logging.Formatter. For example:

formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
file_handler.setFormatter(formatter)
