Python Program to Add Two Matrices

# Program to add two matrices using nested For loop

# 3x3 Matrix 1
X = [[6,7,3],
    [4 ,11,6],
    [7 ,8,9]]

# 3x3 Matrix 2
Y = [[8,8,1],
    [6,6,3],
    [4,5,9]]

# Output Matrix 
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]

print("\nOutput of Addition of Two Matrices:")
for r in result:
   print(r) 

Output of Addition of Two Matrices:
