  • Python 1.6

    ...Python will be released under a GPL-compatible license if at all possible. See CNRI's Python 1.6 License FAQ for answers to frequently asked questions about the CNRI license. Python 1.6 is no longer the latest Python release: Python 2.0 has been released and work has begun on Python 2.1. A "bugfix release" named Python 1.6.1 has been released. This is the first step towards solving the GPL incompatibility. Download The final version of Python 1.6 is available for download n...

  • Python 1.6.1

    ...Python 1.5.x cannot be used with Python 1.6; these extensions will have to be rebuilt for Python 1.6. On Windows, attempting to import a third party extension built for Python 1.5.x results in an immediate crash; there's not much we can do about this. Check your PYTHONPATH environment variable! Overview of Changes since 1.5.2 For this overview, I have borrowed from the document "What's New in Python 2.0" by Andrew Kuchling and Moshe Zadka: http://starship.python.net/crew/amk/python/...

  • What's new in Python 2.3

    ...Python 2.3 What's new in Python 2.3 Here are the (subjective) highlights of what's new in Python 2.3. Faster According to a couple of simple benchmark, Python 2.3 is about 20-30% faster than Python 2.2.3. Some of this speed-up was obtained by removing the SET_LINENO opcodes, which means that the difference is less impressive when comparing "python -O"; the rest was various careful tune-ups. New Tools A brand new version of IDLE (from the IDLEfork project at SourceForge) is now ...

  • Unifying types and classes in Python 2.2

    ...Python ever, and yet it can be done with very few backwards incompatibilities. The changes are described in minute detail in a series of PEPs (Python Enhancement Proposals). PEPs are not designed to be tutorials, and the PEPs describing the type/class unification are sometimes hard to read. They also aren't finished yet. That's where this paper comes in: it introduces the key elements of the type/class unification for the average Python programmer. A bit of terminology: "classic Pyt...
