combining 2D arrays to 3D arrays

Question

Hello I have 3 numpy arrays as given below.

>>> print A
[[ 1.  0.  0.]
 [ 3.  0.  0.]
 [ 5.  2.  0.]
 [ 2.  0.  0.]
 [ 1.  2.  1.]]
>>> pri         


        

Answer 1

I think I got something that works :

>>> print np.hstack([A[:, None, :], B[:, None, :], C[:, None, :]])
[[[ 1  0  0]
  [ 5  9  9]
  [ 0  0  0]]

 [[ 3  0  0]
  [37  8  9]
  [ 0  6  0]]

 [[ 5  2  0]
  [49  8  3]
  [ 1  4  6]]

 [[ 2  0  0]
  [ 3  3  1]
  [ 6  2  0]]

 [[ 1  2  1]
  [ 4  4  5]
  [ 0  5  4]]]
