How do I set up basic logging in Python?

To set up basic logging in Python, you can use the built-in logging module. Here's a simple 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')

What do the different logging levels mean?

The logging levels indicate the severity of events:

• DEBUG: Detailed information, typically for diagnosing problems.
• INFO: Confirmation that things are working as expected.
• WARNING: An indication that something unexpected happened, but the program is still running.
• ERROR: Due to a more serious problem, the software has not been able to perform a function.
• CRITICAL: A very serious error, indicating that the program may be unable to continue running.

Can I log messages to a file instead of the console?

Yes, you can log messages to a file by specifying a filename in the basicConfig method. For example:

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