Kivy - One of the more interesting projects, the liberal MIT-licensed Kivy is based on OpenGL ES 2 and includes native multi-touch for each platform and Android/iOS. It’s an event-driven framework based around a main loop, and is thus very suitable for game development.
Pyforms - At just two years old (making it one of the more recent frameworks), Pyforms is a Python 2.7/3.x cross-environment framework for developing GUI applications. It is modular and encourages code reusability with minimal effort.
libavg - This is another third-party library, written in C++ and scripted from Python, with properties of display elements as Python variables, a full-featured event handling system, timers (setTimeout, setInterval), support for logging and more. Like Kivy, libavg uses OpenGL and makes use of hardware acceleration.
