Appendix A. The Python Ecosystem
This book doesn't attempt to answer all the questions that you might have had about Kivy, or exemplify every remotely possible approach to writing a Kivy app; it should instead serve as a practical, hands-on introduction to writing various programs with a user interface in Python.
Kivy's major achievement is bridging the gap between a Python toolchain and mobile app development on Android and iOS. Unlike bindings to Qt (PyQt and PySide), Kivy is inherently Pythonic (apart from minor implementation details such as the Window
object). These two aspects alone make Kivy a viable option to consider when writing your next user-facing application.
This notwithstanding, I strongly encourage you to explore the vast Python ecosystem. It just so happens that a great many Python modules manage to stay under the radar. Kivy is actually one of them, overshadowed by, for example, the relatively more popular Qt framework (they clearly don't belong...
