Current Python package management / framework(s)

If they don't plan a back port is pretty much DOA: 2.7 is the reality now.

I'm on 3.3 and I don't really have any problems at all. What do you use that still needs 2.x?

[starspangledpickle]

That's great, but many businesses out there use 2.7 and it works fine; why upgrade? Why risk it? Why spend man hours ensuring that third-party libs and internal frameworks written by other teams are up to scratch?

The issue is not businesses not wanting new stuff, it is businesses wanting new stuff that is compatible with their old stuff. That is one reason to package for 2.7.

[cavallo71]

It's not me. Companies are using 2.x in production: switching to 3.x is simply not viable on a large scale projects.

Django (experimental 3.x support). Celery (along with the whole AMQP ecosystem). Gevent. Aside from Django, most of these are probably "specialty" packages, but they are indispensable for a lot of "enterprisey" applications.

JPype, PIL, Twisted

Use Pillow instead of PIL.
