I have an idea germinating that involves using fuzzy logic, something I only had a passing knowledge of. After reading the Wikipedia articles and Googling for it I'm more informed but still haven't found a perfect resource.
The only Python code I have found was informative, but it was from way back in 1990. If there are any Pythonistas who know of a more up-to-date fuzzy logic module, or fuzzy logic resource in general, please let me know!
