transpose matrix numpy

>>> a = np.array([[1, 2], [3, 4]])
>>> a
array([[1, 2],
       [3, 4]])
>>> a.transpose()
array([[1, 3],
       [2, 4]])
>>> a.transpose((1, 0))
array([[1, 3],
       [2, 4]])
>>> a.transpose(1, 0)
array([[1, 3],
       [2, 4]])

transpose matrices numpy

import numpy as np

A = [1, 2, 3, 4]
np.array(A).T # .T is used to transpose matrix
