Who this book is for
This book is intended for programmers who are comfortable with the Python language and who want to build desktop and mobile applications with a rich graphical user interface in Python with minimal hassle. Knowledge of Kivy, while certainly won't hurt, is not required—every aspect of the framework is described when it's first used.
At various points in this book, we will make an analogy between Kivy and web development practices. However, an extensive knowledge of the latter also isn't required to follow the narrative.
