title: subprocess.popen( ) executing Python script but not writing to a file
body: <p>I am trying to run a Python program from inside another Python program using these commands:</p>
  
  <ol>
  <li><p><code>subprocess.call(self.runcmd, shell=True)</code>;</p></li>
  <li><p><code>subprocess.Popen(self.runcmd, shell=True)</code>; and</p></li>
  <li><p><code>self.runcmd = " python /home/john/createRecordSet.py /home/john/sampleFeature.dish "</code> </p></li>
  </ol>
  
  <h2>Now the script runs fine but the file its supposed to write to is not even getting created, i'm using "w" mode for creating and writing</h2>
