title: Opening IDLE from Terminal
body: <p>I'm new to programming and to be more specific, Python. I was going through the installation process from Robert Sedgewick's <a href="http://introcs.cs.princeton.edu/python/mac/" rel="nofollow noreferrer">Introduction to Programming in Python website</a> until right before the section "Downloading and Installing the Booksite Library". My problem occurred with:</p>
  
  <blockquote>
    <p>In the Terminal window issue the command idleX.Y (for example, idle2.7). If an IDLE window appears, then you have installed IDLE properly. Close the IDLE window.</p>
  </blockquote>
  
  <p>As I was installing Python 2.7, I attempted to use the command <code>idle2.7</code>, but I received <a href="https://i.stack.imgur.com/H05KX.png" rel="nofollow noreferrer">the following response</a>. As far as I can tell, I followed all of the directions provided by Mr. Sedgewick's website and I have already verified that Python was being installed as version 2.7.10. After looking for answers online, I found a similar one <a href="https://stackoverflow.com/questions/35249159/macports-idle-unresponsive">here on Stack Overflow</a>. Unfortunately, the potential solutions listed for that question didn't help resolve my issue. At this point, I should mention that I am trying this on a MacBook Pro (2015 model) running the latest version of OS X (El Capitan).</p>
  
  <p>Thanks for your help!</p>
