"Python" not recognised as a command
<p>I just downloaded and installed Python 2.7.2 to my laptop and I am trying to run some sample programs. My laptop is running Windows XP.</p>

<p>When I open a <code>cmd</code> window and type <code>python</code> I get:</p>

<blockquote>
  <p>'python' is not recognized as an internal or external command, operable program or batch file.</p>
</blockquote>

<p>I am not a Windows person (mostly mainframes). However I am guessing that there is some command that I need to execute to define python as a command. Can anyone tell me what that command is?</p>

<p>The installer placed Python at <code>C:\Python27\</code>.</p>
