TL;DR

pyglfw is a Python wrapper around GLFW that handles window creation and keyboard/mouse input for graphics apps, so you can focus on drawing with OpenGL instead of platform windowing code.

Why would anyone build with this?

REASON 1

Open a window in Python and respond to keyboard and mouse events without writing platform-specific code.

REASON 2

Build a lightweight foundation for a 3D graphics demo or data visualization tool using OpenGL for drawing.

REASON 3

Prototype a simple game window and input loop in Python before adding a full game engine.

REASON 4

Use as a thin, low-overhead windowing layer instead of a heavier Python graphics framework.
