Go to http://python.org/ download/ and download the latest version of Python 2.7 (2.7.1 at the time of writing). Unless you know otherwise, get the "Windows Installer" version, and not the "Windows X86-64 Installer" version.</li>
<li>Start up a command prompt by clicking on the Start menu , clicking the "Run..." option, typing "cmd", and hitting enter. If you are using Windows Vista, you should click on the Start menu, type "cmd " into the Search field directly above the Start menu button, and click on "cmd" in the search results above the Search field. </li>

Required step: Put Python on the PATH ==
You might have noticed that you typed a
directory name above when launching Python. In this step, you will reconfigure your computer to put Python on the system PATH so that you can run it without typing the ''Python27'' directory name.
'''This will take about 5 extra minutes''', and it is ''essential'' to an easy life using Python down the road.
(Note: These steps are based on a '''[http://www.youtube.com/watch?v=g9JvseacxPY video that we recommend you watch]'''. They should work equally well on Windows XP, Vista, and 7.)
