Add two Matrix in Python

# Program to add two matrices using nested loop
X = [ [12,7,3],
[4 ,5,6],
[7 ,8,9] ]
Y = [ [5,8,1],
[6,7,3],
[4,5,9] ]
result = [ [0,0,0],
[0,0,0],
[0,0,0] ]
# iterate through rows
for i in range(len(X)):
# iterate through columns
for j in range(len(X[0])):
result[i][j] = X[i][j] + Y[i][j]
for r in result:
print(r)


Output:
[17, 15, 4]
[10, 12, 9]
[11, 13, 18]
