You're not really countering what he said by naming something in the 5%. Yes, there's slightly different string behavior when working with unicode, most things return iterators instead of lists, and print is now a function.

Going from knowing Python 2 to 3 is far easier than going from not knowing Python or programming at all to knowing Python 3.

Python 2 still comes pre-installed on most everything. So, why can't someone coming to Python with little or no experience just be welcomed to use what they have for now?

I kid you not, some of these Python3'ers would have a newb bike shed for a week getting a whole Python 3 workflow with virtual environments, etc going before they'd let the person write their first hello, world. They can learn that stuff later, when it matters.

So, why can't someone coming to Python with little or no experience just install the latest version?

Just shedding some light on both sides of the argument. I'd prefer people starting out use the latest version because it is not hard to install Python 3 and takes very little effort.
