DuraPy - An Open-Source Python Toolbox for STEM Workflows | By Draconis

DuraPy is a growing toolbox for science, engineering, and STEM workflows. It brings together helpful utilities for mathematics, physics, robotics, chemistry-adjacent calculations, and more under one Python universal package.

What makes it useful

• A practical math layer for geometry, trigonometry, and algebra
• Physics constants and helper modules for scientific exploration
• A lightweight foundation for future CLI tools and engineering utilities
• A simple package structure that is easy to extend

Installation

pip install durapy
