title: Python os.name return nt on windows 7
body: <p>Python os.name returns "nt" on windows 7</p>
  
  <p>I'm using os.name to get the name of current operating system under which current script is running. But strangely, instead of "windows 7" it returns "nt".</p>
  
  <p>Here is the code:</p>
  
  <pre><code>import os
  
  print(os.name)
  </code></pre>
  
  <p>And result:</p>
  
  <pre><code>nt
  </code></pre>
