Think Python (How to think like a computer scientist) - Excercise 8.4
<p>I'm having some trouble solving the problem below (My thinking on how I might solve it is directly beneath the problem)</p>

<blockquote>
  <p>"In Robert McCloskey’s book Make Way
  for Ducklings, the names of the
  ducklings are Jack, Kack, Lack, Mack,
  Nack, Ouack, Pack, and Quack."</p>
</blockquote>

<p>This loop outputs these names in order:</p>

<pre><code>prefixes = 'JKLMNOPQ' 
suffix = 'ack'
for letter in prefixes:
    print letter + suffix
</code></pre>

<p>The output is:</p>

<pre><code>Jack
Kack
Lack
Mack
Nack
Oack
Pack
Qack
</code></pre>

<p>Of course, that’s not quite right because “Ouack” and “Quack” are misspelled. </p>

<p>Exercise 8.2 Modify the program to fix this error."</p>

<p>So prefix + suffix yields 4 characters in its current form. Ouack and Quack are 5 characters. In the prior section, we used 'while' to transverse a string to create a condition where if the index is equal to the length of the string, the condition is false, and the body of the loop is not executed. I'm thinking I need to modify the for loop so that if the output character count is less than the original string value inputted, it adds the letter 'U'. How do I go about relating the length of the string value inputted for each name and the 'prefixes'?</p>

<p>I'm not sure how I'd go about doing this, or if I should persue a different strategy.</p>

<p>I apologize in advance I've butchered any of the terminology, I'm two days into this book, and I have no prior computer science background.</p>
