addition of 2 matrices python code example

Example 1: addition of two matrices in python

num = [2, 3, 4], [5, 6, 7]
num2 = [8, 9, 10], [11, 12, 13]
num3 = [0, 0, 0], [0, 0, 0]
for i in range(len(num)):
    print(num[i])
for i in range(len(num)):
    print(num2[i])
print()
for i in range (len(num)):
    for j in range(len(num)+1):
        num3[i][j] = num[i][j] + num2[i][j]

for i in range(len(num3)):
    print(num3[i])

Example 2: addition of matrices 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)
