Yes. It means Python is no longer using Mercurial. We knew this was a done deal a several weeks ago. Mozilla, Octave, and Hedgewars are a few remaining projects that still use hg. For them, I will continue to improve, promote, and use Mercurial. Their reasoning for using Github have nothing to do with the technical merits of git or hg or with the freedom of the software or platform. They want more contributions and they figure using the popular platform is the way to obtain them.
