Jpp Python Package

Project description

The jppy Python package

This software provides Python access to functionalities in Jpp, like accessing PDF functions.

It currently depends on a few Jpp headers (no Jpp compilation needed) and on ROOT TMath (a compiled ROOT installation is needed).

Note: Beware that this package is WIP!


The package can be installed via pip:

pip install jppy

or directly from the Git repository to get the latest stable from the master branch:

pip install git+

or from a local clone:

git clone
pip install jppy/

Example - Using PDFs

Here is an example how to play around with muon PDFs using the jppy module in Lyon. Notice that jppy is already installed in the jpp/master module:
