An example of using Category Encoders.

category_encoders_example.py

# import the packages
import numpy as np
import pandas as pd
import category_encoders as ce

# make some data
df = pd.DataFrame({
 'color':["a", "b", "a", "c"], 
 'outcome':[1, 2, 3, 2]})

# split into X and y
X = df.drop('outcome', axis = 1)
y = df.drop('color', axis = 1)

# instantiate an encoder - here we use Binary()
ce_binary = ce.BinaryEncoder(cols = ['color'])

# fit and transform and presto, you've got encoded data
ce_binary.fit_transform(X, y)
