Python Feature Engineering Cookbook

How to do it...

We'll begin by importing the required libraries, loading the dataset, and preparing the train and test sets:

1. Import pandas and the required scikit-learn class and function:

import pandas as pdfrom sklearn.datasets import load_bostonfrom sklearn.model_selection import train_test_split

2. Let's load the Boston House Prices dataset from scikit-learn into a pandas dataframe:

boston_dataset = load_boston()data = pd.DataFrame(boston_dataset.data, columns=boston_dataset.feature_names)data['MEDV'] = boston_dataset.target

3. Let's divide the data into train and test sets:

X_train, X_test, y_train, y_test = train_test_split(    data.drop('MEDV', axis=1), data['MEDV'], test_size=0.3, random_state=0)

4. Let's learn the mean values from the ...
