numpy - How to transpose a 3D list in python? -


let's have matrix m of dimensions 9 x 9 x 26:

[[['a00', ... 'z00'], ['a01', ... 'z01'], ... ['a09', ... 'z09']], [['a10', ... 'z10'], ['a11', ... 'z11'], ... ['a19', ... 'z19']], ... [['a90', ... 'z90'], ['a91', ... 'z91'], ... ['a99', ... 'z99']]]

i want convert following matrix of dimensions 26 x 81:

 [['a00', 'a01', ... 'a09', 'a10', ... 'a19', ... 'a99'],   ['z00', 'z01', ... 'z09', 'z10', ... 'z19', ... 'z99']]

what's best way of doing in python?

if have list , not numpy array:

m = [[['a00',  'z00'], ['a01',  'z01'],  ['a09',  'z09']], [['a10',  'z10'], ['a11',  'z11'],  ['a19',  'z19']],    [['a90',  'z90'], ['a91',  'z91'],  ['a99',  'z99']]]  itertools import chain print zip(*(chain(*m))  [('a00', 'a01', 'a09', 'a10', 'a11', 'a19', 'a90', 'a91', 'a99'),  ('z00', 'z01', 'z09', 'z10', 'z11', 'z19', 'z90', 'z91', 'z99')]
