How to make modern GUI like VScode, chrome in python?

Question

i use tkinter and pyqt both gui look very old

Answer 1

There's a lot of ways to make PyQt look much more modern. Kivy can be a good option if you're looking for something else.
Vscode is made with electron using HTML-CSS-JS, and there's something like that for python called cefpython. You can give it a try if you want.
