title: Python Subprocess Empty Output
body: <p>I have this code:</p>
  
  <pre><code>pprocess = subprocess.Popen('PROGRAM', stdout=subprocess.PIPE)
  
  while True:
      output = pprocess.stdout.readline()
      print 'output = ', output
  </code></pre>
  
  <p>But the output is not being printed using the python code, but instead it is being printed <strong>on the console</strong> and it appears to be printed directly from the process.</p>
  
  <p>Does anyone came across this issue?</p>
