title: os.path.split(path) is replacing numbers with letters. Help me prevent that
body: <p>I am using the os module to manipulate some files but have run into an issue. The module appears to be replacing all the strings of 106 with an 'f'. </p>
  
  <pre class="lang-py prettyprint-override"><code>import os
  k = "R:\106xx  2300 Delaware\10628\10628-001\F5 - Drawings and Specifications\DOC\Fire Marshal Wet Signed"
  parts = os.path.split(k)
  print(parts)
  </code></pre>
  
  <p>I was hoping for something like </p>
  
  <p>(R:\106xx  2300 Delaware\10628\10628-001\F5 - Drawings and Specifications\DOC\, "Fire Marshal Wet Signed")</p>
  
  <p>instead the output is:</p>
  
  <p>('R:Fxx  2300 DelawareF28F28-001\F5 - Drawings and Specifications\DOC', 'Fire Marshal Wet Signed')</p>
  
  <p>where did the 'F's come from? How do I avoid this?</p>
