Can you provide examples of using the Python logging module?

Sure! The Python logging module is used to log messages from your application. Here’s a simple example:

import logging

# Set up basic configuration
logging.basicConfig(level=logging.DEBUG)

# Log messages of different severity levels
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 are the different logging levels?

The logging levels in Python are:

• DEBUG: Detailed information, typically of interest only when diagnosing problems.
• INFO: Confirmation that things are working as expected.
• WARNING: An indication that something unexpected happened, or indicative of some problem in the near future.
• ERROR: Due to a more serious problem, the software has not been able to perform some function.
• CRITICAL: A very serious error, indicating that the program itself may be unable to continue running.

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

You can log messages to a file by specifying a filename in the basicConfig method. Here’s an example:

import logging

# Set up logging to a file
logging.basicConfig(filename='app.log', level=logging.DEBUG)

logging.debug('This message will go to the file')
