Any Sites For Easy Premade Scripts?

I was wondering if anyone could suggest any websites I could used for easy pre-made scripts. I’ll probably be moving away from Blender’s game engine and therefore from Python shortly, but in the mean-time I have come upon a major opportunity which would be much easier to take advantage of if I had a way to find a script which I could put on a camera which caused Blender’s executable game files to open as two windows (different cameras) on the same scene.

(If you need/want more details of why I need this feel free to PM me.)
