Peak detection in a 2D array
...;> a[1:,1:]
array([[4, 5],
[7, 8]])
Now imagine you stack them one above the other and sum elements at the same positions. These sums will be exactly the same sums over the 2x2 squares with the top-left corner in the same position:

If you're only going one level deep, a nested comprehension will also work:
