 at the top of functions. Docstrings are denoted by
          triple-quotes at the beginning of a function or class:</p>

        <blockquote>
          <p>Good</p>
        </blockquote>

        <pre><code>def average(fn, samples):
    &quot;&quot;&quot;Calls a 0&#x2d;argument function SAMPLES times, and takes
    the average of the outcome.
    &quot;&quot;&quot;</code></pre>

        <p>You should not put docstrings in the middle of the function -- only put them at
          the beginning.</p>
