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:
