The jppy Python package
This software provides access to the PDF functionalities in Jpp. It depends on
some Jpp headers (no Jpp compilation needed) and on the ROOT TMath (a
compiled ROOT installation is needed).
Note: Beware that this package is in the development phase, so the API will
change until version 1.0.0 is released!
Installation
Run make to compile the Python modules:
makeExample
Here is an example how to play around with muon PDFs using the jppy module:
In [1]: import jppy
In [2]: jppy.pdf.JMuonPDF?
Docstring: <no docstring>
Init docstring: __init__(self: jppy.pdf.JMuonPDF, file_descriptor: str, TTS: float, number_of_points: int = 25, epsilon: float = 1e-10) -> None
File: ~/dev/pybind/jppy.pdf.cpython-37m-x86_64-linux-gnu.so
Type: pybind11_type
