Transposing a 3D list in Python

Question

I have to transpose a 3d list the following way:

Input:

matrix7 = [[[\'A \', \'E \', \'C#\'], [\'B \', \'E \', \'C#\'], [\'C \', \'E \', \'C#\']], 
[         


        

Answer 1

I think this is what you want:

numpy.transpose(matrix7, axes=(1, 0, 2)).tolist()  # The 'axes' attribute tells transpose to swaps axes 0 and 1, leaving the last one alone.

OUTPUT:

[[['A ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', '  ', '  '], ['  ', 'E ', 'C#']],
[['B ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', '  ', '  '], ['  ', 'E ', 'C#']],
[['C ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', 'E ', 'C#'], ['  ', 'F#', 'D '], ['  ', 'E ', 'B '], ['  ', '  ', '  '], ['  ', 'E ', 'C#']]]
