copied!<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>
