title: Call python without annoying window
body: <p>I call python from lua script this way:</p>
  
  <pre><code>for i=2000,2018 do
  --prepare settings file for python
  os.execute("C:\\InstallPython\\python.exe C:\\py+lua\\parser.py")
  --work with database downloaded by python
  end
  </code></pre>
  
  <p>Everything works fine, but I get annoying window every time Lua executes python script</p>
  
  <h2>1. Black window appears on each iteration 2. Black window dissapears on each iteration</h2>
  
  <p>How can I do it </p>
  
  <h2>1. without opening window or 2. call this window one time</h2>
  
  <p>Lunatic Python doesnt work for me due to problem described here: <a href="https://github.com/bastibe/lunatic-python/issues/67" rel="nofollow noreferrer">https://github.com/bastibe/lunatic-python/issues/67</a></p>
