title: Conform long lines to fit PEP 8
body: <p>I have a question about styling in PEP 8 (or cutting the number of characters in each line to be smaller).</p>
  
  <p>Consider that I have a <code>book</code> with a bunch of different attributes and I want to concatenate them into some String.</p>
  
  <pre><code>books = [book_1, book_2, book_3]
  for b in books:
    print("Thank you for using our Library! You have decided to borrow %s on %s. Please remember to return the book in %d calendar days on %s" %    
    (book.title, book.start_date, book.lend_duration, book.return_date"))
  </code></pre>
  
  <p>How can I shorten this line to ensure its readability?</p>
  
  <p>Any ideas will help. PEP 8 is just 1 idea.</p>
