Thanks for finding the info Terry. It's about what I expected, a typical S-shaped adoption curve: https://en.wikipedia.org/wiki/Sigmoid_function You start with a few early adopters, which takes a long time to grow, but once it hits a certain critical mass of popularity, there is a sudden and rapid period of growth until the great majority are using the new technology. According to the standard technology adoption life-cycle, we're now in the period where the Late Majority are moving to Python 3. By 2020, I expect that will be complete, and we'll enter a long period as the Laggards slowly convert over a period of about five years. https://en.wikipedia.org/wiki/Technology_adoption_life_cycle https://ondigitalmarketing.com/learn/odm/foundations/5-customer-segments- technology-adoption/ So I expect that by 2025, the percentage of people using 2.x will drop below 1% and by 2030 the numbers using 2.x will be about the same as those using 1.x. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
