Python:

def factors(matrix, factor):

The matrix is a 3D list of integers.

factors are either one, two, or three

If the factor is 'one' it will return a the first value from each list

if the factor is 'two' it will return the second value, and same for the third.

Example;

input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],

[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],

[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ], 'one')

output = [ [1, 3, 9], [0, 8, 5], [0, 5, 3] ]

The answer to this question is as follows:

The code is as follows:

def function(matrix,factor):
l=[]
if(factor=='one'):
for i in matrix:
f=[]
for j in i:
f.append(j[0])
l.append(f)
elif(factor=='two'):
for i in matrix:
f=[]
for j in i:
f.append(j[1])
l.append(f)
elif(factor=='three'):
for i in matrix:
f=[]
for j in i:
f.append(j[2])
l.append(f)
return l

input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],
[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],
[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ]
print("The output is",function(input,'two'))

The input and output is providd in the screenshot below:
