How can I customize logging in Python?

You can customize logging in Python by configuring the logging module. What specific aspects do you want to customize?

I want to change the log format and set different log levels.

You can use logging.basicConfig() to set the log format and level. For example:

import logging
logging.basicConfig(format='%(asctime)s - %(levelname)s - %(message)s', level=logging.DEBUG)

Can I log to a file instead of the console?

Yes, you can log to a file by specifying the filename parameter in basicConfig(). For example:

logging.basicConfig(filename='app.log', format='%(asctime)s - %(levelname)s - %(message)s', level=logging.DEBUG)

What if I want to log messages of different severity levels?

You can create different loggers for different severity levels. For example, use logger.setLevel(logging.INFO) for info messages and logger.setLevel(logging.ERROR) for error messages.
