Kivy Tutorial
Kivy is a graphical user interface Python library that allows you to develop multiplatform applications on Windows, MacOS, Android, iOS, Linux, and Raspberry Pi. What is better is that it performs better then HTML5 cross platform alternatives. Here I’ll show how to install it on both MacOS and Windows. We will also make a few sample apps to make sure everything works.
All of the instructions follow the video below in print form. The code is down there as well.
