**What it does**

class sklearn.preprocessing.LabelEncoder

Encode target labels with value between 0 and n_classes-1.

This transformer should be used to encode target values, i.e. y, and not the input X.

Attributes: classes : ndarray of shape (n_classes,)
Hold the label for each class.
LabelEncoder can be used to normalize labels.

It can also be used to transform non-numerical labels (as long as they are hashable and comparable) to numerical labels.

Methods

fit_transform(y)

Fit label encoder and return encoded labels.

Parameters: y: array-like of shape (n_samples,)

Returns: y: array-like of shape (n_samples,)
