Python library for functional programming

In plain words

This Python library provides tools for functional programming paradigms, enabling developers to write code using functional techniques within Python. It was launched in 2017 and is available on GitHub. The library is designed for Python developers who want to apply functional programming concepts like immutability, pure functions, and compositional patterns to their projects.
