Pyglet

Pyglet is written entirely in Python. Images, video, and sound files in a range of formats can be done natively but can also be expanded with the libav and ffmpeg libraries. It requires no external dependencies.

Text display and formatting

• Rich text formatting (bold, italic, underline, color change, background color, indent, lists) (pyglet.text.formats)
• Built-in layouts to support editable text
• Carets (pyglet.text.caret.Caret)
• HTML support (pyglet.text.layout.IncrementalTextLayout)

Image and sprite work

• Fast image processing and rendering
• Built-in sprites (pyglet.sprite)
• Animated images (*.gif)

Graphics

• OpenGL shaders supported
• Simple built-in shapes (rectangles, circles, triangles) (pyglet.shapes)
• Batched rendering (pyglet.graphics.Batch)
• 3D model rendering

Events and file system

• Resource management (pyglet.resource)
• Clock for processing events and time (pyglet.clock.Clock)
• Window events (pyglet.window.Window)
• Event dispatching (pyglet.event.EventDispatcher)
• Context management

Sprites, text layouts, and text functions are implemented. Multi-level lists are supported and can be created using HTML. Different sections of the displayed document can have distinct styles. A built-in caret provides support for text editing, resembling many features of a UI text input caret.

In this example, lines 1-2 import the pyglet module's necessary components. Line 4 creates a window, and line 6 calls pyglet to run its event loop. Optionally an update rate (in frames per second) can be specified in a rate parameter.
