Pyglet is a cross-platform windowing and multimedia library for Python which provides interface to the platform's OpenGL library.

Pyglet has built-in support for mouse and keyboard events, and can load several multimedia file formats (optionally via AVbin). OpenAL, DirectSound or ALSA can be used for audio playback, with 3D positional audio support.

Pyglet is divided into several interdependent modules such as pyglet.gl, pyglet.graphics, pyglet.image, pyglet.media, pyglet.text, and pyglet.window.
