    My compact solution…

    import sys
import numpy as np

print(np.loadtxt(sys.stdin.readlines()[1:], int).sum(axis=0).prod())

    If the import lines didn't count, this could be considered a one-liner.

    import numpy

array_list =[]
N, M = map(int, input().split())
for _ in range(N):
    arr= list(map(int, input().split()))
    array_list.append(arr)
    
numpy_array= numpy.array(array_list)
np_sum= numpy.sum(numpy_array, axis= 0)
np_product_of_sum= numpy.prod(np_sum)

print(np_product_of_sum)

    l =[] for i in range(n): l.append([int(x) for x in input().split()]) a = numpy.array(l) print(numpy.sum(a,axis =0).prod())

    import numpy as np

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

val = np.array([list(map(int, input().split())) for i in range(n)])

print(np.prod(np.sum(val, axis=0)))
