toolz

toolz is a Python library providing a collection of utility functions for iterators, functions, and dictionaries, extending Python's standard `itertools` and `functools`. It promotes a functional programming style with features like composable, pure, and lazy operations. The current version is 1.1.0, and while the project is alive and maintained for critical bug fixes and Python version bumps, it is generally considered 'inactive' by its maintainers, who view it as mostly complete.
