What's the difference between using a logging module and print statements?

Using a logging module provides more control and flexibility than print statements. It allows for different log levels, better formatting, and the ability to easily disable or redirect output.

Can you give me an example of when to use logging instead of print?

Sure! If you're debugging a production application, using logging allows you to keep track of errors without exposing sensitive information, while print statements might clutter your output.

Are there performance differences between the two?

Yes, logging can be more efficient, especially if you set it to only log messages above a certain severity level. Print statements always execute, which can slow down your application.

What are some common logging libraries I can use?

Some popular logging libraries include Python's built-in logging module, Log4j for Java, and Winston for Node.js.
