title: Why does calling natsorted not modify my list?
body: <pre><code>from natsort import natsorted
  
  filelist=[]
  filelist=os.listdir("C:\\Users\\Amit\\Downloads\\Compressed\\trainigVid")
  natsorted(filelist)
  print filelist
  </code></pre>
  
  <p>I am getting following output</p>
  
  <pre><code>['1.avi', '10.avi', '11.avi', '12.avi', '13.avi', '14.avi', '15.avi',   '16.avi', '17.avi', '18.avi', '19.avi', '2.avi', '20.avi', '21.avi', '22.avi', '23.avi', '24.avi', '3.avi', '4.avi', '5.avi', '6.avi', '7.avi', '8.avi', '9.avi']
  </code></pre>
  
  <p>I want this list to be naturally sorted like</p>
  
  <pre><code>[1.avi, 2.avi, 3.avi.....]
  </code></pre>
  
  <p>I am stuck,please help</p>
