title: Find partial class names in spans with Beautiful Soup
body: <p>This page <a href="https://www.kijiji.ca/v-1-bedroom-apartments-condos/ville-de-montreal/1-chambre-chauff-eau-chaude-incl-vsl-514-856-0038/1334431659" rel="noreferrer">https://www.kijiji.ca/v-1-bedroom-apartments-condos/ville-de-montreal/1-chambre-chauff-eau-chaude-incl-vsl-514-856-0038/1334431659</a> contains this span class:</p>
  
  <pre><code>&lt;span class="currentPrice-3131760660"&gt;&lt;span content="800.00"&gt;800,00 $&lt;/span&gt;
  </code></pre>
  
  <p>I'm trying to automatically extract the price (800$ in this case). Over time, however, the number after "currentPrice-" changes, and my Python script ceases to work. I am using this Beautiful soup function:</p>
  
  <pre><code>soup.find_all('span', {'class' : 'currentPrice-3131760660'})
  </code></pre>
  
  <p>How can I use find_all to extract partial matches of class names, such as all classes containing the string "currentPrice-"?</p>
