LABEL ENCODING : converting categorical data to numerical data

import numpy as np
import pandas as pd

from sklearn import preprocessing

Import dataset
df = pd.read_csv('C:\Vinuthna\python_enthu\Iris.csv')
print(df['species'].unique())

#Encode the Labels in Species Column

label_encoder = preprocessing.LabelEncoder()
df['species']= label_encoder.fit_transform(df['species'])

print("After Encoding")
print(df['species'].unique())

OUTPUT:
['setosa' 'versicolor' 'virginica']
After Encoding
[0 1 2]
