None of PyPy, Unladen Swallow or IronPython are dependencies for Python 3.x to be "ready for prime time". Neither is C module support. Python 3.1 itself is solid, reliable release of the Python language. It and the standard library are more than ready to be put into production. Of course, if you personally require some C module "ham" which only supports 2.6, you'll have good reason to stick with 2.6. But then if your project absolutely depends on module "spam" which only supports Python 1.5, you'll be still using Python 1.5. So what? For the rest of us, you can do a lot with just Python 3.1, with or without C modules. Whether it does *enough* to be considered for deployment depends on what you're deploying it to do. I for one would not hesitate to use Python 3.1 as a scripting language, or for any application where the standard library is all you need. You can do a lot with just the standard library. For the rest, the question isn't "is Python 3 ready for production?", because the answer for that is "absolutely". The question is, "are the libraries I need ready for Python 3?", and the answer to that is often No, but sometimes a provisional or experimental Yes. Personally, I'm getting tired of all the negative nellies who seem to think that take up of Python 3 is a race, and that if anyone is still using 2.x by next Tuesday that means Python 3 is a failure and we should all just dump it as a bad idea. Python 3 uptake is not a race. Both Python 2.7 and 3.x will be supported for many years to come. If you can't use 3 *now*, that's fine, nobody says you should -- but by the same token, try to tone down the negativity. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
