**Python Program to Transpose a Matrix**: In this example, you will learn to transpose a matrix (which is created by using a nested list).

In Python, we can implement a matrix as a nested list (list inside a list). We can treat each element as a row of the matrix.

For example: **X = [[1, 2], [4, 5], [3, 6]]** would represent a** 3×2 matrix. **The first row can be selected as **X[0].** And, the element in the first-row first column can be selected as **X[0][0].**

**Source Code**

```
# Program to transpose a matrix using a 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)
```
