PyWeek - day 5 - Anyone got Perlin Noise?

Wow, day 5 went really badly. I spent the day paralysed by the looming deadline, trying to code a part of my program that I thought would be fast and easy to code but has turned out to be difficult; random functions. Perlin noise is really complicated for a stressed out brain! If anyone has a Perlin noise implementation in Python I would really appreciate knowing about it!

Erm, why don't you use the internal randoms? Is this Perlin-noise that much important for gameplay? Like: 

import random
random.gauss(main, deviance)
random.randrange(a,b)

Cheers!

"""Perlin noise is a procedural texture desgined by Ken Perlin. It's (pseudo)random, it doesn't repeat. It's band-limited, so the texture has a sort of uniform "roughness", and there are no large-scale features when you look at it from afar. So it's pretty much the happenin' thing to use when you have stuff you don't want to look flat."""

Cool, thank you for the info! :)

Obviously there's some python code there, I hope it's useful.

Good luck!
