title: Separate initials from full name input in python without using split
body: <p><em>EDIT</em> This was my first post and I completely forgot to show what I had already tried. I wasn't looking for a complete program, just suggestions on methods I could use to concatenate initials. <em>EDIT</em></p>
  
  <p>I need to create a program that allows a user to input their full name and only prints the initials. This must be done <strong>WITHOUT USING .SPLIT OR LISTS</strong></p>
  
  <p>From my hw:
  Write a program that gets a string of a person's full name – <code>first</code>, <code>middle</code>, and <code>last name</code> and then displays their initials.
   Create a function <code>getInitials()</code>. </p>
  
  <pre><code>&gt;&gt;&gt;Enter your full name: James Tiberias Kirk
  &gt;&gt;&gt;J.T.K. 
  </code></pre>
