Urgent! Question on python, matrix operations, Thank you!

3. Finally, add support for option 5, which replaces the existing matrix with its transpose The transpose of an n x m matrix is a new m x n matrix in which the rows of the original matrix become the columns of the new one, and vice versa Begin by writing a function transpose(matrix) that takes the specified 2-D list matrix and creates and returns a new 2-D list that is the transpose of matrix. The original 2-D list should not be changed For example: >>>matrix-[[1, 2, 3], [4, 5, 6]] >>print_matrix(matrix,) 1.00 2.00 3.00 4.00 5.00 6.00 >>>transp - transpose(matrix) >>>transp >>print_matrix(transp.) 1.004.00 2.00 5.00 3.00 6.00 The function should begin by creating a new matrix with the necessary dimensions. You may want to use (and possibly adapt) one or more of the functions from Problem 1 for this purpose. If you do so, you should copy the necessary functions into ps10pr2.py Once the new matrix is created, iterate over its cells and set their values to the appropriate values from the original matrix. Make sure that you return the new matrix! Because we aren't changing the contents of the existing matrix, but rather are creating a new matrix, we need to return it so that it can be used by the caller of the function
