How can I customize the log format in Python?

You can customize the log format in Python using the logging module. You can set a format string when configuring the logger.

Can you show me an example of how to set a custom format?

Sure! Here's a simple example:

import logging

logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)
logger = logging.getLogger(__name__)
logger.info('This is an info message')

What other options can I include in the format string?

You can include options like %(filename)s, %(funcName)s, and %(lineno)d to log the filename, function name, and line number respectively.

Is it possible to log to a file with a custom format?

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

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