stack list of numpy arrays code example

Example 1: np.stack

>>> a = np.array([1, 2, 3])
>>> b = np.array([2, 3, 4])
>>> np.stack((a, b))
array([[1, 2, 3],
       [2, 3, 4]])

Example 2: converting list of arrays with same size to single array python

LIST=[[array([1, 2, 3, 4, 5]), array([1, 2, 3, 4, 5],[1,2,3,4,5])]
numpy.concatenate( LIST, axis=0 )
