=====Function Descriptions=====
sum
The sum tool returns the sum of array elements over a given axis.
import numpy
my_array = numpy.array([ [1, 2], [3, 4] ])
print numpy.sum(my_array, axis = 0)         #Output : [4 6]
print numpy.sum(my_array, axis = 1)         #Output : [3 7]
print numpy.sum(my_array, axis = None)      #Output : 10
print numpy.sum(my_array)                   #Output : 10
By default, the axis value is None. Therefore, it performs a sum over all the dimensions of the input array.
prod
The prod tool returns the product of array elements over a given axis.
import numpy
my_array = numpy.array([ [1, 2], [3, 4] ])
print numpy.prod(my_array, axis = 0)            #Output : [3 8]
print numpy.prod(my_array, axis = 1)            #Output : [ 2 12]
print numpy.prod(my_array, axis = None)         #Output : 24
print numpy.prod(my_array)                      #Output : 24
By default, the axis value is None. Therefore, it performs the product over all the dimensions of the input array.
=====Problem Statement=====
ou are given a 2-D array with dimensions NXM.
Your task is to perform the sum tool over axis 0 and then find the product of that result.
=====Output Format=====
Compute the sum along axis 0. Then, print the product of that sum.
import numpy as np

n, m = [int(x) for x in input().strip().split()]
array = np.array([[int(x) for x in input().strip().split()] for _ in range(n)])
print(np.prod(np.sum(array, axis = 0)))
import numpy as np

n, m = [int(x) for x in input().strip().split()]
array = np.array([[int(x) for x in input().strip().split()] for _ in range(n)])
print(np.prod(np.sum(array, axis = 0)))
