I apologize ahead if my question is very basic. I'm still new to python. I have the code snippet where Len(cls) is 27 and I want to split this len=27 array into an array of arrays each of len=3. The code snippet below splits it into an array of shape (9,3) but I would like an array of shape (3,3,3). Is there a way to do this? Thanks

new_cls_list=[] 
for j in range(len(cls)):
    new_cls_list_1=[]
    k=0
    while k<len(cls[j]):
        new_cls_list_1.append(cls[j][k:k+3])
        k+=3
    new_cls_list.append(new_cls_list_1)

Have a look at `numpy.reshape`. – hilberts_drinking_problem Dec 12 '18 at 01:51

Try `np.reshape(cls, (3,3,3))` – hpaulj Dec 12 '18 at 01:51
You can try `[array[i:i + 3] for i in range(0, len(array), 3)]` – Dimitrios Mavrommatis Dec 12 '18 at 02:21
