Return a :term:`slice` object representing the set of indices specified by
``range(start, stop, step)``. The *start* and *step* arguments default to
``None``. Slice objects have read-only data attributes :attr:`~slice.start`,
:attr:`~slice.stop` and :attr:`~slice.step` which merely return the argument
values (or their default). They have no other explicit functionality;
- however they are used by Numerical Python and other third party extensions.
+ however they are used by NumPy and other third party packages.
Slice objects are also generated when extended indexing syntax is used. For
example: ``a[start:stop:step]`` or ``a[start:stop, i]``. See
:func:`itertools.islice` for an alternate version that returns an iterator.
