What you need for this book
We're going to focus on Python 3, exclusively. Many computers will have Python 2 already installed, which means an upgrade is required. Some computers don't have Python installed at all, which means that a fresh installation of Python 3 will be necessary. The details are the subject of Chapter 1, Getting Started.
It's important to note that Python 2 can't easily be used to run all of the examples. Python 2 may work for many of the examples, but it's not our focus.
In order to install software, you'll generally need administrative rights on the computer you intend to use. For a home computer, this is generally true. For computers supplied through work or school, administrative passwords may be required.
You may also want to have a proper programmer's text editor. Default text editing applications such as Windows Notepad or Mac OS X TextEdit can be used, but aren't ideal. There are numerous free text editors available: feel free to download several to locate the one that feels most comfortable for you.
