In this Python program, we will learn how to multiply two matrices.

Here is the code of the program to multiply two matrices.

```
# Program to multiply two matrices using nested For loops
# 3x3 matrix
X = [[6,7,3],
[4 ,11,6],
[7 ,8,9]]
# 3x4 matrix
Y = [[5,8,1,2],
[6,7,3,0],
[4,5,9,1]]
# Output is 3x4
result = [[0,0,0,0],
[0,0,0,0],
[0,0,0,0]]
# iterate through rows of X
for i in range(len(X)):
# iterate through columns of Y
for j in range(len(Y[0])):
# iterate through rows of Y
for k in range(len(Y)):
result[i][j] += X[i][k] * Y[k][j]
print("\nOutput of Multiplication of Two Matrices:")
for r in result:
print(r)
```

Output of Multiplication of Two Matrices:

[84, 112, 54, 15]

[110, 139, 91, 14]

[119, 157, 112, 23]

```
# Program to multiply two matrices using list comprehension
# 3x3 matrix
X = [[6,7,3],
[4 ,11,6],
[7 ,8,9]]
# 3x4 matrix
Y = [[5,8,1,2],
[6,7,3,0],
[4,5,9,1]]
# Output is 3x4
result = [[sum(a*b for a,b in zip(X_row,Y_col)) for Y_col in zip(*Y)] for X_row in X]
print("\nOutput of Multiplication of Two Matrices:")
for r in result:
print(r)
```

Output of Multiplication of Two Matrices:

[84, 112, 54, 15]

[110, 139, 91, 14]

[119, 157, 112, 23]
