Converting Categorical Variables to Numerical Values | Label Encoding

We have shown here two ways to convert categorical variables or Label Encoding. One with Scikit-learn's LabelEncoder utility class And another way is, using Numpy where() Method.

LabelEncoder class encodes target labels with a value between 0 and the number of variables-1. This transformer should be used to encode the target variable, Y, and not the input data, X.

The Numpy where() method is especially good for encoding where there are only two types of categorical variables.
