Reexamining Python 3 Text I/O. Python 3.1’s IO performance is a huge improvement over 3.0, but still considerably slower than 2.6. It turns out it’s all to do with Python 3’s unicode support: When you read a file in to a string, you’re asking Python to decode the bytes in to UTF-8 (the new default encoding) at the same time. If you open the file in binary mode Python 3 will read raw bytes in to a bytestring instead, avoiding the conversion overhead and performing only 4% slower than the equivalent code in Python 2.6.4.

Current State of Unladen Swallow (Towards a Faster Python). The Unladen Swallow team are now planning to merge their work back in to the mainline Python 3 branch, adding a powerful incentive for Python developers to port their old Python 2 code (since the official Python 2.x line is extremely unlikely to have Unladen Swallow merged in to it).

What’s New In Python 3.1. Lots of stuff, but the best bits are an ordered dictionary type (congrats, Armin), a Counter class for counting unique items in an iterable (I do this on an almost daily basis) and a bunch of performance improvements including a rewrite of the Python 3.0 IO system in C. 28th June 2009, 3:02 pm
Dive into Python 3. Mark Pilgrim’s seminal work taught me Python nearly eight years ago. Now he’s updating it to cover Python 3. It’s just a table of contents at the moment, but the chapter on “Packaging Python libraries” has me very excited.

I don’t think that Python 3.0 is a bad thing. But that it’s displayed so prominently on the Python web site, without any kind of warning that it’s not going to work with 99% of the Python code out there, scares the hell out of me. People are going to download and install 3.0 by default, and nothing’s going to work. They’re going to complain, and many are going to simply walk away.

Python 3.0. “We are pleased to announce the release of Python 3.0 (final), a new production-ready release, on December 3rd, 2008.” 4th December 2008, 12:38 pm
String types in Python 3. bytes are now immutable (just like the bytestrings they are replacing) and a new mutable buffer type has been introduced. 9th October 2007, 2:08 am
Sam Ruby: 2to3. Sam’s report on an attempt to port the Universal Feed Parser to Python 3.0. The 2to3 tool does most of the work, but it seems the unicode changes can be pretty tricky. 3rd September 2007, 1:38 am
What’s New in Python 3.0. They’re definitely taking advantage of the break in backwards compatibility—lots of niggling inconsistencies are finally being cleaned up. 1st September 2007, 1:41 am
Python 3.0a1 released. Wow, that was a pretty fast turnaround. Betas are planned for 2008, with a final release scheduled for August. 31st August 2007, 8:36 pm
