title: How to get synonyms from nltk WordNet Python
body: <p>WordNet is great, but I'm having a hard time getting synonyms in nltk. If you search similar to for the word 'small' like <a href="http://wordnetweb.princeton.edu/perl/webwn?o2=&amp;o0=1&amp;o8=1&amp;o1=1&amp;o7=&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=&amp;s=small&amp;i=3&amp;h=00100000000000000#c" rel="noreferrer">here</a>, it shows all of the synonyms.  </p>
  
  <p>Basically I just need to know the following:
  <code>wn.synsets('word')[i].option()</code> Where option can be hypernyms and antonyms, but what is the option for getting synonyms?</p>
