title: Python's os.listdir behaviour on Windows
body: <pre><code>&gt;&gt;&gt; import os
  &gt;&gt;&gt; os.chdir('c:/python27')
  &gt;&gt;&gt; os.listdir('c:')
  ['Tools', 'include', 'python.exe', 'libs', 'DLLs', 'Lib', 'NEWS.txt',
  'w9xpopen.exe', 'Doc', 'pythonw.exe', 'LICENSE.txt', 'README.txt', 'tcl']
  &gt;&gt;&gt; os.listdir('c:/')
  ['users', 'Program Files', 'Python27', 'windows']
  </code></pre>
  
  <p>Why is the "/" after "c:" affecting the outcome? Is there a way to get <code>os.listdir('c:')</code> to return the contents of "c:/"?</p>
