EPANET Python Toolkit (EPyT)\n\nThe `EPANET-Python Toolkit` is an open-source software, originally developed by the [KIOS Research and Innovation Center of Excellence, University of Cyprus](http://www.kios.ucy.ac.cy/) which operates within the Python environment, for providing a programming interface for the latest version of [EPANET](https://github.com/OpenWaterAnalytics/epanet), a hydraulic and quality modeling software created by the US EPA, with Python, a  high-level technical computing software. The goal of the EPANET Python Toolkit is to serve as a common programming framework for research and development in the growing field of smart water networks.\n\nThe `EPANET-Python Toolkit` features easy to use commands/wrappers for viewing, modifying, simulating and plotting results produced by the EPANET libraries.  \n\nFor support, please use the OWA community forum: https://github.com/orgs/OpenWaterAnalytics/discussions\n\n## Table of Contents\n\n- [EPANET Python Toolkit (EPyT)](#epanet-python-toolkit-epyt)\n- [How to cite](#how-to-cite)\n- [Requirements](#requirements)\n- [How to install](#how-to-install)\n- [How to use the Toolkit](#how-to-use-the-toolkit)\n- [How to fix/report bugs](#how-to-fixreport-bugs)\n- [Licenses](#licenses)\n- [Contributors](#contributors)\n- [Contributing](#contributing)\n- [Recommendation](#recommendation)\n- [List of EPyT Functions](#list-of-epyt-functions)\n- [List of EPANET 2.2 Functions](#list-of-epanet-2012-functions-supported)\n- [List of EPANET 2.3 Functions Supported](#list-of-epanet-23-functions-supported)\n- [List of EPANET MSX Functions API](#list-of-epanet-msx-functions-api)\n\n## How to cite \n\nKyriakou, M.
