ArtistThe array arr_3d is different from arr_2d in that it is a 3D array with three dimensions: depth, rows, and columns. arr_3d has a shape of (2, 2, 3), meaning it has 2 depth levels, each with 2 rows and 3 columns. In this case, arr_3d can be thought of as a "stack" of two 2D arrays. Each of these 2D arrays has 2 rows and 3 columns, as indicated by the two pairs of square brackets inside the larger outermost brackets.
