As others have mentioned the PyPI statistics aren't random at all. They're a count of downloads based on user agents. The points I mentioned above were discussions I had with the maintainer of PyPI (Donald Stufft) who also recognises that aggregated counts from PyPI are not an effective measure. There are no good stats that give an accurate representation about usage % of each python version. PyPI is the only proxy we have, and that is skewed by a number of factors (two of which I mentioned). The overall trend is probably accurate, but exact percentages certainly are not. My like or dislike for python 2 or 3 has nothing to do with my comment upthread. I was simply stating a number of facts about the data that people can take or leave as they like. It was not "convenient" for me to share those facts. I simply thought people might want to be aware that there's nothing scientific about the aggregated percentages.
