(return_X_y=False)[source]¶ Load and return the wine dataset (classification).
New in version 0.18.
The wine dataset is a classic and very easy multi-class classification dataset.
Classes 3 Samples per class [59,71,48] Samples total 178 Dimensionality 13 Features real, positive Read more in the User Guide.
Parameters: return_X_y : boolean, default=False.
If True, returns
(data, target)
instead of a Bunch object. See below for more information about the data and target object.Returns: data : Bunch
Dictionary-like object, the interesting attributes are: ‘data’, the data to learn, ‘target’, the classification labels, ‘target_names’, the meaning of the labels, ‘feature_names’, the meaning of the features, and ‘DESCR’, the full description of the dataset.
(data, target) : tuple if

Examples
Let’s say you are interested in the samples 10, 80, and 140, and want to know their class name.
>>> from sklearn.datasets import load_wine >>> data = load_wine() >>> data.target[[10, 80, 140]] array([0, 1, 2]) >>> list(data.target_names) ['class_0', 'class_1', 'class_2']
