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. And, the element in the first-row first column can be selected as X.
Python Program to Transpose a Matrix
# 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)): result[j][i] = X[i][j] for r in result: print(r)
