🚀 Feature Request

I found many print statements on the code, what do you think about replacing it with logger?

🔈 Motivation

logger is more organized rather than print.

Thank you for your interest!

There is no debugging content yet, so logging has not been set.
We will replace the logger when various issues arise.
