title: Can't resolve WindowsError: [Error 2] The system cannot find the file specified
body: <p>I'm trying to rename all the pictures in a directory. I need to add a couple of pre-pending zero's to the filename. I'm new to Python and I have written the following script.</p>
  
  <pre><code>import os
  
  path = "c:\\tmp"
  dirList = os.listdir(path)
  
  for fname in dirList:
      fileName = os.path.splitext(fname)[0]
      fileName = "00" + fname
      os.rename(fname, fileName)
      #print(fileName)
  </code></pre>
  
  <p>The commented print line was just to verify I was on the right track. When I run this I get the following error and I am at a loss how to resolve it.</p>
  
  <blockquote>
    <p>Traceback (most recent call last):   File

  <p>Any help is greatly appreciated. Thnx.</p>
