Installing Python On Windows

October 9th, 2012 by Erin Scott

Intro

Python, although a standard language for all Macs and most Unix / Linux distributions, doesn’t come preinstalled on windows machines. Thankfully, getting the python to play nice with Bill Gates is very straightforward and you’ll be done in less time it takes to run a Windows update.

Get Python 2.7.3

First step is to go to the main python website and get the correct python version for your needs. Although python 3.2 is out python 2.7.3 is the most compatible and version 3.2 isn’t 100% backwards compatible so unless you’re writing code from scratch that won’t need any external modules version 2.7.3 is the way to go.

Get the specific python installer for your hardware here: http://www.python.org/getit/

Installing Python

Installing is simple. Open the MSI package like so:

Install Python 2.7.3

Choose the install folder. Default is C:\Python27

Choose folder

Default customizations are fine

Then watch some progress bars…

All done!
Finished!

 

Updating Your Path (optional & recommended)

The only other thing you may need to do is update your path to include the python executable. This isn’t necessary since the installer associates all .py files with the python exe but if you ever want to test something or just run python from the shell this update is a handy one.

First, right click the My Computer icon and go to properties.

Then go to advanced.

Append ;C:\Python27 to the path section like so.

All done!
