Python 3.0

Python 3.0 is end-of-lifed with the release of Python 3.1. All users of Python 3.0.x should upgrade to the most recent version of Python 3; please see the downloads pages.

Python 3.0 has been replaced by a newer bugfix release of Python. Please download Python 3.0.1 instead.

Python 3.0 final was released on December 3rd, 2008.

Python 3.0 (a.k.a. "Python 3000" or "Py3k") is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places.

[1]	The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).
