[edit] Download and install Python

If you believe you already have Python installed, please let a staff member know before completing these steps.

  1. Click http://python.org/ftp/python/2.7.1/python-2.7.1.msi and choose "run" if you have the option to. Otherwise, save it to your Desktop, then minimize windows to see your desktop, and double click on it to start the installer. Follow the installer instructions to completion.
  2. Open a command prompt (we will be doing this multiple times, so make a note of how to do this!):
    • On Windows Vista or Windows 7: click on the Start menu (the Windows logo in the lower left of the screen), type cmd into the Search field directly above the Start menu button, and click on "cmd" in the search results above the Search field.
    • On Windows XP: click on the Start menu (the Windows logo in the lower left of the screen), click on "Run...", type cmd into the text box, and hit enter.

    You now have what's called a command prompt. This command prompt is another way of navigating your computer and running programs -- just textually instead of graphically. We are going to be running Python and Python scripts from this command prompt.
  3. At this C:\ prompt that appears, test your Python install by typing
    \Python27\python.exe
    

    and hitting enter. You should see something like

    Python 2.7.1 (r271:86832, ...) on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>>
    

    You just started Python! The >>> indicates that you are at a new type of prompt -- a Python prompt. The command prompt let's you navigate your computer and run programs, and the Python prompt lets you write and run Python code interactively.

  4. To exit the Python prompt, type
    exit()
    
    and press Enter. This will take you back to the Windows command prompt (the C:\ you saw earlier).


[edit] Success!

You have Python installed and configured.
