It's not a marketing campaign but the normal process of migrating from one version to a newer, incompatible, version. It also depends on what platform you're developing for. On Red Hat boxes 2.6.6 is the "standard" for RHEL 6. From what I understand, RHEL 7 will not be Python 3 yet, either. If you don't have any platform restrictions, then 3.3 is the way to go.

Is this just a well managed marketing campaign? Python 2.7 is alive and well and will be supported for quite a few more years yet. But it is a dead end. There will be no Python 2.8. It will continue to get bug fixes for a few more years, and security updates for a few years longer, but no new features. Meanwhile, Python 3.3 and beyond is where the future is at. New features and performance improvements are all aimed at 3.3. The reason for the two parallel "current versions" is that Python 3 introduced a few language changes which broke backward compatibility, and rearranged the standard library to make it more consistent. Since these were big changes, it is tricky (but not impossible!) for a single program to run under both Python 2 and Python 3. Realizing that it would take the big libraries many years to migrate to Python 3, the Python development team committed to keeping 2.7 alive for longer than normal, so as to give people time to migrate. I estimate that we're about half-way into the process. More than half of the big libraries have either started, or completed, migrating to support 3.x. At least one Linux distribution uses Python 3 as their system Python, and most of the others provide it as an optional extra. So, maybe another 4-5 years of life in Python 2.7? If you are just starting out, and have no prerequisites about external libraries, you should stick with Python 3.3. Please do not use Python 3.0, it is slow and buggy and not supported. 3.1 or 3.2 are acceptable, but if you have a choice, go for 3.3. If you need a specific library which does not support Python 3, then 2.7 is acceptable. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

[Tutor] Python version 2.7 or 3.0
Hey all, I'm used to python 2.7 but I'm seeing and hearing a lot about 3.0 and wanted to ask a few questions. I'm seeing on StackOverflow that 2.7 is the standard for those that have libraries that haven't been ported to 3.1.2 yet. Does this mean that 2.7 is dead or dying? Is this just a well managed marketing campaign? If these can be simplified into layman's terms I'd really appreciate your advice & input. -- ~MEN ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
