How to load Wine Dataset using Sklearn?

The sklearn.datasets.load_wine() function allows you to load the Wine dataset directly into NumPy arrays or pandas DataFrame objects. By setting the return_X_y and as_frame parameters, you can control the format of the returned data.

Syntax: sklearn.datasets.load_wine(*, return_X_y=False, as_frame=False)

In the following code, we utilize the pandas library to load the wine dataset from scikit-learn’s built-in datasets module. It converts the dataset into a pandas DataFrame, allowing easy manipulation and analysis.

Python
import pandas as pd
from sklearn.datasets import load_wine

# Load the wine dataset into a DataFrame
wine_data = load_wine(as_frame=True)
wine_df = wine_data.frame

print(wine_df.head())

# Display the shape of the DataFrame
print("Shape of the Wine DataFrame:", wine_df.shape)

Output:
