HackerRank- Python Mean, Var, and Std


Calculate Min, Var and Std of a 2-D array



  1. import numpy as np 

  2. 

  3. n,m = map(int, input().split())

  4. b = []

  5. for i in range(n):

  6.     a = list(map(int, input().split()))

  7.     b.append(a)

  8. 

  9. b = np.array(b)

  10. 

  11. np.set_printoptions(legacy='1.13')

  12. print(np.mean(b, axis = 1))

  13. print(np.var(b, axis = 0))

  14. print(np.std(b))
