genno: efficient, transparent calculation on N-D data

genno is a Python package for describing and executing complex calculations on labelled, multi-dimensional data. It aims to make these calculations efficient, transparent, and easily validated as part of scientific research.

genno is built on high-quality Python data packages including dask, xarray, and pint; and provides (current or planned) compatibility with packages including pandas, matplotlib, plotnine, ixmp, sdmx1, and pyam.

A 玄能 (genno or gennoh) is a type of hammer used in Japanese woodworking. The package name is warning, by reference, to the adage “When you hold a hammer, every problem looks like a nail”: you shouldn’t hit everything with genno, but it is still a useful and versatile tool.
