Given that even a relatively inexperienced developer can easily port 2,500+ lines of Python 2 to Python 3 per day, there&#x27;s really very little reason for anyone to still be on Python 2 regardless of the benefits or lack thereof of Python 3. This is especially true if you&#x27;re not trying to take advantage of all the performance benefits of Python 3 right away, and are content just to wrap iterators in list() or whatever just to get the functionality working the same without much effort.
