## Python 3.X ## Python 3.X
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 many deprecated features have been removed. In addition, the standard library has been reorganized in a few prominent places. Python 3.0 (a.k.a.
