I'm so old that Fortran was actually my first language. Over the years I've seen language bindings to the old Fortran numerical libraries we all rely on but Python/numpy is the first wrapper I've actually enjoyed using. It's more than a wrapper in that it brings a compact representation of slices and vectors. However, if I didn't know how things work underneath I'd be a little uneasy. You can always profile after the fact but it helps knowing how to avoid inefficient approaches.
