Create an application¶ Creating a kivy application is as simple as: sub-classing the App class. implementing its build() method so it returns a Widget instance (the root of your widget tree) instantiating this class, and calling its run() method.

pos : pos stands for position i.e it is used to position the widget . By default (0, 0), the bottom-left corner of the screen is the default position of the button in kivy python.

Module: kivy.app. The App class is the base for creating Kivy applications . Think of it as your main entry point into the Kivy run loop. In most cases, you subclass this class and make your own app.

The KV language, sometimes called kvlang or the kivy language , allows you to create your widget tree in a declarative way and to bind widget properties to each other or to callbacks in a natural manner. It allows for very fast prototypes and agile changes to your UI.
