Use logging instead of print

[alexgarel]

We use print in the current code to display message.

This is not a good practice:

• if you don't add flush=True, message get printed at random moment
• we can't add debug print and decide to ignore them easily
• we won't be able to send log errors to sentry if we set it up

[alexgarel]

We need to have a way to setup logging (but BasicConfig should do as a first approach).

Hey! This seems like an interesting issue for someone like me who's trying to learn and understand about logging. Do you mind if I take this issue up? Also, I may need some assistance.
