pycodata 2.2.0

pycodata: CODATA constants for python.

Introduction

Python wrapper around the Fortran codata library. The Fortran library does not need to be installed, the python wrapper embeds all needed fortran dependencies for Windows and MacOS. On linux, you might have to install libgfortran if it is not distributed by default with your linux distribution.

Installation

In a terminal, enter:

pip install pycodata
