Jpp Python Package
Project description
The jppy Python package
This software provides Python access to functionalities in Jpp, like accesing 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!
Installation
The package can be installed via pip directly from the Git repository:
pip install git+https://git.km3net.de/km3py/jppy
or from a local clone:
git clone https://git.km3net.de/km3py/jppy pip install jppy/
Example - Using PDFs
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 Subclasses: In [3]: Do you really want to exit ([y]/n)? n In [3]: muon_pdf = jppy.pdf.JMuonPDF("/pbs/throng/km3net/src/Jpp/master/data/J%p.dat", 0) loading input from file /pbs/throng/km3net/src/Jpp/master/data/J1p.dat...
