Expansion Functions

These four private Python library expansions introduce a combined 400 new functions, with 100 functions developed for each of functools, os, pathlib, and sys. The collection significantly broadens these established libraries while preserving their respective areas of specialization, providing a larger set of streamlined tools for everyday development, automation, system interaction, runtime management, and more advanced Python workflows. Rather than replacing the foundations of the original libraries, the expansions build upon them with practical capabilities intended to reduce repetitive code, simplify common operations, and give developers a more extensive set of reusable functions within four important areas of Python programming.

There is approximately 7000 callable functions and methods in a default Windows Python 3.14 installation.
