Python How to return position of Non-zero elements of a matrix in python

Hi,
I have for example this matrix:
1 0 -1 4
0 1 4 0
3 3 2 1
0 0 1 -1
by this code:
Python:
for i in range(n):
    a =[]
    for j in range(n):
         a.append(int(input()))
    adjacency_matrix.append(a)

Now, how to return position of Non-zero elements of adjacency_matrix in Python?
I want to save (0,1) (1,0) (1,3) (3,0) (3,1), for example
x : array for rows
y: array for columns
x = [0 1 1 3 3]
y= [1 0 3 0 1]
