At the time of writing this document the current version of the Python interpreter software is version 3. Please note that Python 3 is ***NOT*** compatible with some earlier versions of Python. Be aware that there are some significant differences between Python 3 and earlier versions. For beginner Python programmers, the main ones are that the print statement of Python 2.x is now a print function in Python 3, the raw_input function in Python 2.x is replaced by the input function in Python 3, and an integer division such as 2/3 in Python 2.x is now a real division in Python 3. For experienced programmers, also check out the range() and string formatting differences outlined here: http://inventwithpython.com/appendixa.html A full list of differences between Python 2.x and Python 3 can be found here: http://docs.python.org/3.0/whatsnew/3.0.html. Newer versions of Python 3 will be released in the future. Newer versions of Python 3 will (hopefully) be backward compatible - which means that if you write Python programs using version 3, they should still run using future versions of the Python 3 interpreter. You should always download the latest version of the software as it will contain the latest features and bug fixes.
