The Scikit-HEP project is a collection of several dozen packages intended to facilitate the use of Python in High Energy Physics. One of the major fronts of development is in histogramming; a majority of HEP analysis is heavily reliant on histograms. To this end, a new Python package was introduced for histogramming in Scikit-HEP, boost-histogram. This package is intended to be a core package for histogramming with no dependencies. In this summer, we are preparing to implement an analysis-friendly package, called “hist”, built on top of boost-histogram and providing commonly expected histogramming features. This package will allow a wider range of dependencies and features not admissible in the core package.
