Mean, Var, and Std

Problem link : https://www.hackerrank.com/challenges/np-mean-var-and-std/problem

Difficulty : Easy

Tip

• np.set_printoptions(legacy='1.13')
• Still this is required
• Please understand how to use np.mean(), np.var() and np.std()

Solution

import numpy as np np.set_printoptions(legacy='1.13') N, M = list(map(int, input().split(' '))) arr = np.array([input().split(' ') for _ in range(N)], int) arrM = np.mean(arr, axis = 1) print(arrM) arrV = np.var(arr, axis = 0) print(arrV) print(np.std(arr))
