Maybe this is a joke, and then I'd say it's pretty neat one. I mean, just look at that, what other language got a similar problem of that scale! And let's not pretend it all passed and we are happily moving forward: this year (this month, actually) I've seen very prominent NN-course, suggesting Python 2.7 for all assignments and code samples, and quite useful library (also NN-related), supporting 2.7 only. I guess, some of mitsuhiko's (Ronarcher's) developments didn't move to 3.* as well.

So, yeah, IPython dropping 2.7 is pretty huge. Almost like moving to a different language.

Oh, that's plain silly. Isn't the whole point of Python 2.7 to facilitate the transition to Python 3?

Silly or not, but it's still very common mindset with scientific-oriented people (who care about ML, econometrics, statistics and such much more than "programming" per se), who form a quite notable category of Python users. Actually, for me they are the reason why I'm still using Python a lot (although I try to stick to 3.x), because for other use-cases, like scripting or web-dev I mostly (but not completely) moved to other languages.

What defines python? You purposely ignored the distinctions I clarified in my post.

Let's say I developed a python-like language called "schlython", can I call on the python-2 community to convert all "old" python-2 code into my competing language?

Let's say you developed a Python-like language called Python 2.6, can you call on the Python-2.5 community to convert all old code? Come on, nobody was forced at gunpoint to port to Python 3, that's why there are still abandoned Python 2 projects all over the Cheese Shop.

What conversions are needed for the py2.6 code?

> nobody was forced at gunpoint

The caretakers of py2 are the promoters of py3. Support was dropped for py2 without any serious effort to find new caretakers, so that the demise of py2 would promote switching.

Enough with the conspiracy theories already. There was no reason to find "new caretakers" for Python 2.7 because it's simply an old version of the language.

Reading through your posts here, I don't know what your problem is with the Python team, but please do get over it. It's incredibly annoying dealing with someone who just seems to think they're entitled for more than a decade of support of a version of their free product.

What conspiracy theory - Who decides that py2 needs to be killed off?

> but please do get over it

This is an ad hom - please make your posts more substantial, it feels like you are the one with a chip on your shoulder if you can't respond to these points. Your original comment added nothing to the thread but snark.
