It's hardly shutting down if the support will last another 6 years ...

This seems weird to me. Won't this cause a fork in Python at some point, where the 2.7 developers continue on 2.8 or rename it entirely, and another fork continues on what is now Python 3?

Python 2.7 hasn't has any improvements since python 3 began, and it won't. All this announcment means is that Python 2.7 will continue to get security/support for another 5 years.

Python 2.7 was released after 3.1 and contains many features backported from the 3.x series in order to ease migration.

Nor have I done research on Perl, Scala, etc. Your missing my point. I am successfully getting my things done in Python 2. I do not have any use for Python 3, Perl, Scala, or any other language. I might have in the future, and hey, some language might be better suited to solve the problem - but as long as it's not drastically better the sensible tradeoff is to stick with Python 2.

That philosophy sounds like one that will cause you to wake up one day and realize your skill set is massively out if date. Python 3, scala, and pearl all give you new ways of solving a problem. You're missing out on a lot of super cool stuff by not exploring! Outside of maybe library support, I see no reason to not to at least check out python 3.

Fair point. But I'd like to quote my own post above:

If you prefer to work with a platform that will get only bugfixes/security updates go ahead

Potentially no new libraries (for new things and/or API connections)

Not sure how long new versions of existing libraries will keep 2.7 support.

> I for one like the 2.x style print function. 2.x didn't have a print function, unless you mean the one from 3 available with a from __future__ import.

In case the grandparent doesn't realize, 2.x has a print statement not function.

Actually it's a procedure because it has a side-effect.

This bothers/worries me, because I don't understand where this notion that "learning Python 3" requires significant effort or commitment comes from. Python 3 isn't massively different from Python 2. I learn more "new stuff" (APIs I've never used before, implementation details of systems I work on/with, etc.) basically every month than that difference.

Python 2 -> 3 can be a big step because of dependencies. The difference between the languages themselves is negligible (and yet, IMHO for the better). You don't need to learn any new ways of thinking here.

If you're comfortable with Python 2, you're comfortable with Python 3 as well. If your dep ducks are in a row and you're writing new code, it's an obvious choice.

I meant function as in functionality. This is really pointless nitpicking.

Knowing the difference between functions and statements is not pointless nitpicking. Not in the least.

I think it's a strong signal to industrial users that Python is a stable and mature language whose core developers care about practical usage. Pushing Python 3 for ideological reasons ("it's the right thing to do") would alienate a lot of users who have real work to do and cannot invest weeks to upgrade to a version that does not provide them any benefits.
