The code I referenced measures the difference between strings (percentages), using Levenshtein distance--which states the number of changes between two strings. If you can find a source that states this idea of difference can be attributed to Levenshtein, then by all means I will acknowledge him. Until then, I will refer to Alex Martelli's code.

Exactly, and the algorithm used is, as I said, attributed to Levenshtein. Expressing it as a ratio is hardly novel.
As for the implementation, Alex Martelli credit's Stavros Korokithakis[1], although Lev implementations are 2-a-penny, and this isn't a particularly good one (sorry Stavros).

I cited Levenshtein by name in my original comment. I'm guessing you didn't read everything what I wrote, because I don't understand why you would think there's an issue otherwise.
> Expressing it as a ratio is hardly novel.
The whole reason I linked to Alex Martelli's post is because it's his work, not mine, novel or otherwise. I just cited the resourced I used.
