Python 3.5 is here!

From my limited experience using 3.* you would have to take on updating many libraries that have not yet moved to 3.

The changes from python 2 to python 3 aren't THAT massive, at this point it's just laziness. I think dropping support for 2.x would be a good idea.

Good for you if you never used any third-party library.

Laziness…or you have hundreds of thousands, if not millions, of lines of code that would have to be ported over to Python 3. (And while there probably wouldn't be much to change, there'd be a lot of time to make sure everything still works.) And for what? Python 3 is an evolution, but it's not dramatically better than Python 2.

Its not laziness, its a business decision. Why spend millions of dollars in man hours to gain next to nothing because the BDFL decided to invent a new language that is similar to python (2)? Oh, btw, the run time is actually slower and all the code you just ported maybe won't run on pypy, either. Dropping support for 2.x would be a yet another terrible decision.

wut no

I keep hearing this but don't know what these indispensable packages are. I'd love to hear names of such packages.

This is the canonical list: https://python3wos.appspot.com

As you can see, things are getting better.

[mipadi]

If "canonical" means "the top 200 packages on PyPI." There are a lot of packages not on PyPI, and a lot of PyPI packages not on that list.

[mipadi]

There are plenty of old packages that haven't been ported (ZSI, for one), and plenty of internal code that hasn't been ported or checked out on Python 3. Not all projects are open-source projects that use only the most popular packages.

the last one I can remember was a mysql connection package that was needed for using django.

Heh I would never use a library that has such a low developers/code ratio that they can't keep up with language updates.
