iris.data is the core feature data of the Iris dataset.
In simpler terms:
- It's a NumPy array.
- It contains the measurements (features) for each flower.
- Each row in the array represents a single flower sample.
- Each column in the array represents a specific measurement (e.g., sepal length, sepal width, petal length, petal width).
So, when you print iris.data, you are seeing all the numerical features that describe each of the 150 Iris flowers in the dataset.
