In the real world, things are rarely black and white. There’s often a gray area, a spectrum of possibilities between the extremes. That’s where fuzzy logic comes in — a concept that allows us to model and reason about imprecise or vague information.

Fuzzy logic is particularly useful when dealing with systems that are too complex to be accurately described by traditional boolean logic. Instead of strict true/false values, fuzzy logic operates on degrees of truth, expressed as a value between 0 and 1.

In this article, we’ll explore how to harness the power of fuzzy logic in Python using the scikit-fuzzy library. We’ll walk through a practical example to solidify your understanding.

Setting Up Our Fuzzy Environment

First, let’s install the required library:

pip install scikit-fuzzy

Now, we can import the necessary components:

import numpy as np
import skfuzzy as fuzz
