Slicerator

Slicerator is a Python library that provides a lazy-loading, fancy-sliceable iterable. It allows you to wrap existing classes or functions to make them behave like reusable generators that support advanced slicing (like NumPy arrays), but only load data when explicitly accessed. The current version is 1.1.0, released in April 2022. While releases are not on a strict schedule, it remains a functional and actively used utility in various projects.
