The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix. Example 1: Input:[[1,2,3],[4,5,6],[7,8,9]] Output:[[1,4,7],[2,5,8],[3,6,9]] Example 2: Input:[[1,2,3],[4,5,6]] Output:[[1,4],[...

The result is a series oftuples, where each tuple contains the corresponding elements from the rows of the original matrix. Example 3: Rearrange 2D List Using NumPy In this final example, we will use thetranspose() functionfrom Python’sNumPy libraryto transpose the 2D list. ...
