This article instead teaches ndarray shape reasoning, basic versus advanced indexing, boolean masks, broadcasting rules, singleton axes, keepdims, and systematic shape-error debugging. source check: Reviewed against the current official NumPy user guide on 2026-09-04, especially the broadcasting, indexing, expand_dims, copies/views, and ufunc documentation. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p>
