cypari2 1.0.0

An interface to the number theory library libpari

# CyPari 2

[](https://travis-ci.org/defeo/cypari2)

A Python interface to the number theory library [libpari](http://pari.math.u-bordeaux.fr/).

This library supports both Python 2 and Python 3

## Installation

1. Install libpari

2. Clone the cypari2 project

3) Install with pip: ` $ cd where_I_cloned_cypari2 $ pip install . ` Note that any other kind of installation program is not supported. In particular, python setup.py install does NOT work.

## Usage

Just launch Python and then you can perform some PARI/GP computation inside python ` >>> import cypari2 >>> pari = cypari2.Pari() >>> pari(2).zeta() 1.64493406684823 >>> K = pari("bnfinit(x^3 - 2)") >>> K.bnfunit() [x - 1] `

## Issues

1) If you change your PARI installation you need to recompile cysignals and cypari2 using the –no-cache-dir option of pip

pip install cysignals –no-cache-dir –force-reinstall [–user] pip install cypari2 –no-cache-dir –force-reinstall [–user]
