Mean, Var, and Std

  • [deleted]Challenge Author     + 0 comments

    For Python3

    It itsnt mentioned to round off the std value to 11 decimals. So, use round function just to match the answer.

    import numpy

n, m = map(int, input().split())
arr = numpy.array([input().split() for i in range(n)], dtype=int)

print(numpy.mean(arr, axis=1))
print(numpy.var(arr, axis=0))
print(round(numpy.std(arr), 11))
