title: Python command line (too few arguments)
body: <p>I have a problem with my python system call. I have set up my python, path and pathext.</p>
  
  <p>These commands work on my computer</p>
  
  <pre><code>run.py
  python runWithParamater.py parameterExample.txt
  </code></pre>
  
  <p>but if I run:</p>
  
  <pre><code>runWithParamater.py parameterExample.txt
