I've been trying to scrape a table on Wikipedia using Beautifulsoup, but encountered some problems. 

Page: <https://en.wikipedia.org/wiki/New_York_City>
Table: 
[enter image description here](https://i.stack.imgur.com/SwyBg.png)

Table: "Racial composition"

In the page source, the table seems to start at row 1470.

Here's the code I tried first:

```
website_url = requests.get('https://en.wikipedia.org/wiki/New_York_City').text
soup = BeautifulSoup(website_url,'lxml')
table = soup.find('table',{'class':'wikitable sortable collapsible'})

headers = [header.text for header in table.find_all('th')]

table_rows = table.find_all('tr')        
rows = []
for row in table_rows:
   td = row.find_all('td')
   row = [row.text for row in td]
   rows.append(row)

with open('NYC_DEMO.csv', 'w') as f:
   writer = csv.writer(f)
   writer.writerow(headers)
   writer.writerows(row for row in rows if row)

```

And here's the error:

```
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-24-e6000bdafe11> in <module>
      3 table = soup.find('table',{'class':'wikitable sortable collapsible'})
      4 
----> 5 headers = [header.text for header in table.find_all('th')]
      6 
      7 table_rows = table.find_all('tr')

AttributeError: 'NoneType' object has no attribute 'find_all'

```

I suppose this is code from the Wikipedia page that we'd need to get:

```
<tbody><tr>
<th>Racial composition</th>
<th>2010<sup id="cite_ref-QuickFacts2010_226-1" class="reference"><a href="#cite_note-QuickFacts2010-226">&#91;224&#93;</a></sup></th>
<th>1990<sup id="cite_ref-pop_228-0" class="reference"><a href="#cite_note-pop-228">&#91;226&#93;</a></sup></th>
<th>1970<sup id="cite_ref-pop_228-1" class="reference"><a href="#cite_note-pop-228">&#91;226&#93;</a></sup></th>
<th>1940<sup id="cite_ref-pop_228-2" class="reference"><a href="#cite_note-pop-228">&#91;226&#93;</a></sup>
</th></tr>
<tr>
<td><a href="/wiki/White_American" class="mw-redirect" title="White American">White</a></td>
<td>44.0%</td>
<td>52.3%</td>
<td>76.6%</td>
<td>93.6%
</td></tr>
<tr>
...

```

I'm guessing it can't locate the right table? There's quite some tables on that page so how do I correctly point towards that table?

Thanks in advance for your help.
