title: How to stop Python program execution in IDLE
body: <p>I have a python script that uses <code>plt.show()</code> as it's last instruction. When it runs, IDLE just hangs after the last instruction. I get the image but I don't get the prompt back.</p>
  
  <p>On other scripts I typically use <code>ctrl-c</code> to break the program (sometimes doesn't work immediately) but how do I get the prompt back with the <code>plt.show()</code>? <code>Ctrl-c</code> doesn't work...</p>
  
  <p>Are there other ways to stop the program?</p>
  
  <p>This is IDLE on Windows, if it makes any difference.</p>
