I would like to introduce you to a late pet project of mine - Votelib - and kindly ask you for any feedback you might have.
Votelib is a Python package to evaluate results of common election methods. It focuses on those currently in active use, but some prospective methods are also implemented. At the moment, it supports e.g. most known largest remainder and highest averages proportional systems, transferable vote with Hare and Gregory transfers, Condorcet methods such as Schulze or ranked pairs, Majority Judgment, variants of Borda count, score voting including STAR, approval methods including PAV or SPAV, Bucklin voting or open party list evaluation.
If you are interested, I will greatly appreciate it if you go through it or try to use it and give me any feedback you might have. If you create some code or evaluate some results using it, I will gladly integrate that into the library's test suite. If you find some bugs, please report them at the GitHub issue tracker.
I am neither a voting systems researcher nor a mathematician, so if you have any general comments on the terminology or concepts used, I will be glad to hear them.
And - what would be most wonderful - if you wanted to join in with the library's development, such as implementing one of the many interesting systems I found on Electowiki, I will gladly accept your pull requests!
