title: Get output from Python script in QT
body: <p>I want to run script written in Python and get all output from that.
  This is my cpp code</p>
  
  <pre><code>QProcess process;
  process.setProcessChannelMode(QProcess::MergedChannels);
  QString exe = "python script.py";
  process.start(exe);
  process.waitForFinished(-1);
  QString output(process.readAllStandardOutput());
  
  qDebug() &lt;&lt; output &lt;&lt; endl;
  </code></pre>
  
  <p>and my script.py</p>
  
  <pre><code>import sys
  print("Hello world!")
  </code></pre>
  
  <p>The strange thing is when I change "python script.py" to "ping google.com" it's working like a charm. I checked it also on my cmd, but it seems that my Python installation is also good. 
  Where I'm doing it wrong? </p>
  
  <p>[EDIT 1]
  echo %PATH%</p>
