title: whitespaces in the path of windows filepath
body: <p>I am working on file operations using python.  </p>
  
  <p>I have a filepath as :  </p>
  
  <pre><code>filepath = "E:/ABC/SEM 2/testfiles/all.txt"
  </code></pre>
  
  <p>when I am opening the file using python, it says me :  </p>
  
  <pre><code>IOError: No such file:
  </code></pre>
  
  <p>but, the file is present on the drive.<br>
  It may be because windows cannnot take "SEM 2" properly as it contains space.<br>
  How can I deal with such whitespaces in the path of window path?</p>
