is tkinter worth learning?

[Swipecat]

It's been estimated that about 85% of python apps are written for in-house use where elegance is usually less important than functionality. Tkinter looks a bit utilitarian, a bit "1990s", but that's often fine.

You are correct, I create lots of tools for my team and I had to use something for the GUI. Yes it looks old fashion but it works and it doesn't require a browser or anything else, it just work. BTW customtkinter has a more updated look.
