title: Using findAll in BS4 to create list
body: <p>I'll start by saying I'm sort of new with Python. I've been working on a Slack bot recently and here's where I'm at so far.</p>
  
  <pre><code>source = requests.get(url).content
  soup = BeautifulSoup(source, 'html.parser')
  price = soup.findAll("a", {"class":"pricing"})["quantity"]
  </code></pre>
  
  <p>Here is the HTML code I am trying to scrape.</p>
  
  <pre><code>&lt;a class="pricing" saleprice="240.00" quantity="1" added="2017-01-01"&gt; S &lt;/a&gt;
  &lt;a class="pricing" saleprice="21.00" quantity="5" added="2017-03-14"&gt; M &lt;/a&gt;
  &lt;a class="pricing" saleprice="139.00" quantity="19" added="2017-06-21"&gt; L &lt;/a&gt;
  </code></pre>
  
  <p>When I only use <code>soup.find()</code>, I'm able to find the first quantity value but I need all of them within a list. I looked into using a different library like lxml instead of bs4 but didn't have any luck with that either. Any help is really appreciated as I've already spent a long time on this.</p>
