import numpy
N, M = map(int, input().split()) arr = numpy.array([input().split() for _ in range(N)], int)
print(numpy.mean(arr, axis=1)) print(numpy.var(arr, axis=0)) print(round(numpy.std(arr), 11)) why we must round the std value? because the question not force us to round 11 digits.
For Python3 Platform
It is not mentioned to round the value of standard deviation to 11 digits. I did it just to match the answer
