python - Composing slices into a multidimensional slice for numpy array slicing -

if have 2 slice objects defined along 1 dimension each, possible combine them multidimensional slice object can used slice numpy array?

mat = np.zeros((10,10), dtype=np.uint8) s1 = slice(0,5) s2 = slice(0,5) mat[s1,s2]  # want achieve effect 1 slice object     slice2d = slice(s1, s2)  # not throw error mat[slice2d]  # not work 

as pointed out @unutbu, multi-dimensional slice tuple or list of slice objects, then:

slice2d = (s1, s2) mat[slice2d] 

will work. similarly, can extend 3-d, ..., n-d arrays:

slice3d = (s1, s2, s3) ... slicend = (s1, s3, s3, ..., sn)
