Indexing on ndarrays — NumPy v2.2 Manual

An integer, i, returns the same values as i:i+1 except the dimensionality of the returned object is reduced by 1. In particular, a selection tuple with the p-th element an integer (and all other entries :) returns the corresponding sub-array with dimension N - 1.If N = 1 then the returned object is an array scalar. These objects are explained in Scalars.
