  We announce ChromaStarPy, an integrated general stellar atmospheric modeling
and spectrum synthesis code written entirely in python V. 3. ChromaStarPy is a
direct port of the ChromaStarServer (CSServ) Java modeling code described in
earlier papers in this series, and many of the associated JavaScript (JS)
post-processing procedures have been ported and incorporated into CSPy so that
students have access to ready-made "data products". A python integrated
development environment (IDE) allows a student in a more advanced course to
experiment with the code and to graphically visualize intermediate and final
results, ad hoc, as they are running it. CSPy allows students and researchers
to compare modeled to observed spectra in the same IDE in which they are
processing observational data, while having complete control over the stellar
parameters affecting the synthetic spectra. We also take the opportunity to
describe improvements that have been made to the related codes, ChromaStar
(CS), CSServ and ChromaStarDB (CSDB) that, where relevant, have also been
incorporated into CSPy. The application may be found at the home page of the
OpenStars project: http://www.ap.smu.ca/~ishort/OpenStars/ .
