Currently Font objects have default repr:

<tkinter.font.Font object at 0x7fa22c3bd1e0>

Since Font is just an object oriented wrapper for font name, and Font objects with the same name are equal, it is worth to show the font name in the repr and do not show an id.

<tkinter.font.Font object 'TkDefaultFont'>

Hi, Storchaka!.
I would like to tackle this issue.
Because I am new to Python bug tracking, I am unsure that this is the right approach to bug fixing.

Serhiy, while I agree this is an enhancement, I don't see that it would break *anyone's* code (this will mostly just affect the REPL output) so is it worth considering a backport?

Diohabara, the Python devguide (https://devguide.python.org/) is a very good place to start. The first contribution is always the hardest so please do ask if you need clarification on something. Likely the first thing you will need to do, though, is sign the CLA which means we can legally accept your patch.

This is a new feature. We do not backport new features to old versions unless they fix some design bug. Nothing bad will happen if we DO NOT backport it.
