How can I effectively use logging for debugging in Python?

You can use the built-in logging module in Python to track events that happen during execution. It allows you to log messages at different severity levels.

What are the different logging levels available?

The main logging levels are DEBUG, INFO, WARNING, ERROR, and CRITICAL. Each level indicates the severity of the events.

Can you show me a simple example of how to set up logging?

Sure! Here's a basic example:

import logging

logging.basicConfig(level=logging.DEBUG)

logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')

How can I log messages to a file instead of the console?

You can specify a filename in the basicConfig method like this:

logging.basicConfig(filename='app.log', level=logging.DEBUG)
