Python Machine learning Logistic Regression: Exercise-1 with Solution

Write a Python program to view some basic statistical details like percentile, mean, std etc. of the species of ‘Iris-setosa’, ‘Iris-versicolor’ and ‘Iris-virginica’.

Sample Solution:

Python Code:

import pandas as pd
data = pd.read_csv("iris.csv")
print('Iris-setosa')
setosa = data['Species'] == 'Iris-setosa'
print(data[setosa].describe())
print('\nIris-versicolor')
setosa = data['Species'] == 'Iris-versicolor'
print(data[setosa].describe())
print('\nIris-virginica')
setosa = data['Species'] == 'Iris-virginica'
print(data[setosa].describe())

Sample Output:
