What are the logging formatting options in Python?

In Python, you can customize logging output using the format parameter in the basicConfig method. Common options include %(asctime)s, %(levelname)s, %(message)s, and %(name)s.

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

Sure! You can set a custom format like this:

import logging

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

What does each part of the format string mean?

Here's a breakdown:

• %(asctime)s: Timestamp of the log entry.
• %(name)s: Name of the logger.
• %(levelname)s: Severity level of the log (e.g., DEBUG, INFO).
• %(message)s: The actual log message.

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.INFO)
