title: Error when accessing synonyms in python using nltk?
body: <p>I have written a very simple piece of code to try and print the synonyms associated with a word.</p>
  
  <pre><code>import nltk
  from nltk.corpus import wordnet as wn
  wordNetSynset =  wn.synsets('small')
  for synSet in wordNetSynset:
      for synWords in synSet.lemma_names:
          synonymList.add(synWords)
  print synonymList
  </code></pre>
  
  <p>However, I get the following error: </p>
  
  <pre><code>Traceback (most recent call last):
    File "test.py", line 6, in &lt;module&gt;
      for synWords in synSet.lemma_names:
  TypeError: 'instancemethod' object is not iterable
  </code></pre>
  
  <p>Does anyone know what the problem could be? </p>
