>12 years. It's all been very usable for 6 years. So you had 6 years to use the six or python-future lib, and 6 years to remove it. 100k lines, it's a 2 weeks job if your code is properly tested
It took Flask several years, complaints, and a custom change for their use case, to port over.
Some people have actual production code which they don't rewrite for the fun of it (and even less with comically underestimated "2 weeks per 100K" runs), because the core decided a non-backwards compatible version is the future.
>But good news, you don't have to do it. Python 2.7 will still work after 2020. We, the community, will just stop working on it for free. You can start paying us, or do the job for free like we did since 1991.
Well, you're not the "community", at best you're one committer. The community (not necessarily the core devs) will fork and maintain way beyond 2020, and it will be for free too.
>I'm tired of hearing complains, given how good you have it.
Sorry, didn't know people must walk on tiptoes lest they tire you with their complains...
Well, programming languages evolve and to maintain a clean language (which python aspires to be), it has to cut some ties.
I think the overly backward-compatible way in which the change was managed really prolonged the adtoption and getting python 3.x to mature. The Python-Community was hanging between those versions far too long and it really hurt the ecosystem and the whole python-experience.

Of course, but you (probably) still have to maintain the code. And it's not a full rewrite, more an adaption. I find most changes to be quite mechanical. Also, it's not the python-comunities fault, you chose python and you're getting probably using it for some business purpose. So i think the python community can expect you to maintain it, including language adaptions. You can still ignore this and don't update, but libraries will probably start getting incompatible and there will come a time when things break. Wheter that's important enought to migrat is up to you.
I don't think it's fair to just complain loudly, after all, the python community is not expection a full rewrite. They have given enough time to migrate, i think took much, but it's still a lot. Being completely backward compatible forever was never promised, and i think is an complete anti-feature. Write once and never think about it is not the python-way, but having a clean, smart, elegant language. It also really hurts java, which just walks with all the backage of the past and glacial speed for language-updates, which probably is required when everything you do is going to be kept forever in the language.
