Transpose a Matrix in Python

# Program to transpose a matrix using nested loop
X = [[12,7],
[4 ,5],
[3 ,8]]
result = [[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[j][i] = X[i][j]

for r in result:

print(r)

Output:

[12, 4, 3]
[7, 5, 8]
