I have been running a little static site that visualises the progress of of the Python Community's effort in moving forward to Python3. Great progress has been made, and now the data source has stopped updating. So I have made one last update to the site.
We finish on 95.5% support for Python3. It has been over 10 years since Python3 was released, so this has been a long time coming, but it appears most of the community has moved forward. Just nine packages in the top 200 didn't support Python3 (and there is a chance they do but just aren't marked as such).
The final update was 22 April 2018 (and yes, I only noticed yesterday and I hadn't updated py3progress in over 2 years). I will leave my py3progress site up for as long as I remember it is still there.
If anyone wants nearly 6 years of Python Wall Of Superpowers content (html only), just let me know.
