Contruct 3d array in numpy from existing 2d array

Question

During preparing data for NumPy calculate. I am curious about way to construct:

myarray.shape => (2,18,18)

from:

d1.shape          


        

Answer 1

Just doing d3 = array([d1,d2]) seems to work for me:

>>> from numpy import array
>>> # ... create d1 and d2 ...
>>> d1.shape
(18,18)
>>> d2.shape
(18,18)
>>> d3 = array([d1, d2])
>>> d3.shape
(2, 18, 18)
