Which framework is better

Question

Between Kivy and Qt which of these framework is good for UI development?

Answer 1

Since you have Android in the tag, use kivy. Kivy is built with mobile development in mind. Qt on the other hand have its strength because of the amount of its built-in widgets.

Edit: Additionally, PyQt is more of an API for the Qt toolkit while Kivy is really made for Python. Also, if you're into game development (built-in widgets is not the priority), I suggest Kivy. Here is a link for one of their documented tutorials: https://kivy.org/doc/stable/tutorials/pong.html
