I can not parse html using xpath and lxml library
<p>I`m using Python 3.5.
I want to get a list of synonyms from the site, with the help of XPATH, but I do not get the required html code and get "[]".</p>

<pre><code>import lxml.html
word=input("Input your word: ")
url = "http://www.thesaurus.com/browse/{word}?s=t.html".format(word=word)
html = lxml.html.parse(url)
syn = html.xpath("//DIV[@id='filters-0']")
print(syn)
</code></pre>

<p>If you are good at python, then tell me how to do such a task more concise and simple.
Big thanks!</p>

<p>Just imagining you need Synonyms extracted :</p>

<pre><code>import requests
from lxml import html

source = html.fromstring(((requests.get('http://www.thesaurus.com/browse/wordy?s=t.html')).text).encode('utf-8'))
print (source.xpath('//div[@class="synonym-description"]//text()')[3].strip())
</code></pre>
