 <p>Please try the following:</p> <pre><code>for word in wn.words(): print word </code></pre> <p>This should work because <code>wn.words()</code> is actually an iterator that generates a sequence of strings, rather than a list of strings like <code>b.words</code>. The <code>for</code> loop causes the iterator to generate the words one at a time.</p>
