title: How to do virtual file processing?
body: <p>So for creating files I use the following:</p>
  
  <pre><code>fileHandle = open('fileName', 'w')
  </code></pre>
  
  <p>then write the contents to the file, close the file.
  In the next step I process the file.
  At the end of the program, I end up with a "physical file" that I need to delete.</p>
  
  <p>Is there a way to write a "virtual" file that behaves exactly like a "physical" one (allowing it to be manipulated the same way) but does not exist at the end of the run in Python?</p>
