Python UI Development Kit Kivy
Kivy is an open source toolkit that enables programs created using the same source code to run across platforms. It focuses on innovative user interface development, such as: multi-touch applications. Kivy also provides a multi-touch mouse simulator. Currently supported platforms include: Linux, Windows, Mac OS x, and Android.
Kivy has the ability to handle animations, caching, gestures, graphics, and so on. It also has
In Python, the steps to get started with GUI programming are not complicated, but they require users to start making some choices. As a general-purpose programming language, there are interpreters available for every common operating system, so creating a graphical user interface is not a difficult task for Python. Programmers can have a lot of choices, and the r

Speaking of the python GUI, I am not familiar with it. At present, the main python is mainly to use python to write scripts and web development, which does not involve writing software, but I am going to study Python software development later. After all,
I'd like to introduce you to the simplest way to start GUI programming, which is to use the Scriptics TK and tkinter wrappers. We'll make a lot of comparisons with the curses library mentioned in "Curses programming in Python" in DeveloperWorks. In addition to the difference between curses implementing the text console and TK implementing the GUI, the two librari
