title: run python in terminal using sublime
body: <p>I use Linux Mint 17.3 and recently installed Sublime Text 3 <em>(unregistered version)</em>. In order to run python scripts in terminal <em>(the external terminal of the OS, not the internal one of the IDE)</em> I fount somewhere this:</p>
  
  <p>Tools -> Build system -> New build system</p>
  
  <p>type this:</p>
  
  <pre><code>{
  "cmd": ["gnome-terminal -e 'bash -c \"python3 -u $file;echo;echo Press ENTER to exit; read line\"'"],"shell": true
  }
  </code></pre>
  
  <p>and save it as python3.sublime-build</p>
  
  <p>After that I quit sublime and relaunch it. I open a python file, then select </p>
  
  <p>Tools -> Build system -> python3, and</p>
  
  <p>Tools  -> Build</p>
  
  <p><strong>A terminal window should appear but instead, nothing happens.</strong> </p>
  
  <p>Any suggestions would be appreciated.</p>
