Calling from Python

Using OrnsteinZernike from Python is straighforward

Installing

First, install juliacall through the pip package manager, with

pip install juliacall

This package allows one to call julia from python

In Python (only versions $\geq$ 3 are supported), run:

from juliacall import Main as jl

which will install the latest stable version of Julia the first time it is called. Now install OrnsteinZernike.jl with

jl.Pkg.add("OrnsteinZernike")

To import this package in order to use it we need to run:

jl.seval("using OrnsteinZernike")

The jl.seval function let's us evaluate any julia code from within Python.

Usage

We can now use OrnsteinZernike.jl in Python:

from juliacall import Main as jl
jl.seval("using OrnsteinZernike")
dims = 3
kBT = 1.0
rho = 0.5
potential = jl.HardSpheres(1.0)
system = jl.SimpleLiquid(dims, rho, kBT, potential)
closure = jl.PercusYevick()
sol = jl.solve(system, closure)

import matplotlib.pyplot as plt

plt.plot(sol.r, sol.gr)
plt.xlim(0, 5)
plt.show()

See the documentation of juliacall for more information on how to call Julia from Python.
