The Scikit-HEP project is a community-driven and community-oriented effort with the aim of providing Particle Physics at large with a Python scientific toolset containing core and common tools. The project builds on five pillars that embrace the major topics involved in a physicist’s analysis work: datasets, data aggregations, modelling, simulation and visualisation. The vision is to build a user and developer community engaging collaboration across experiments, to emulate scikit-learn's unified interface with Astropy's embrace of third-party packages, and to improve discoverability of relevant tools. The Scikit-HEP toolset is comprised of the scikit-hep package and numerous third-party “affiliated” packages. These affiliated packages include well-known packages such as root_numpy and root_pandas, but also newer packages that add functionality such as reading ROOT files natively, and interfaces between NumPy and Pythia or FastJet. The project's website is http://scikit-hep.org/ and the GitHub repositories are at https://github.com/scikit-hep. An overview of the overall project, toolset, and main functionality, will be presented.
