title: Python regular expression re.match, why this code does not work?
body: <p>This is written in Python,</p>
  
  <pre><code>import re
  s='1 89059809102/30589533 IronMan 30 Santa Ana Massage table / IronMan 30 Santa Ana Massage table'
  pattern='\s(\d{11})/(\d{8})'
  re.match(pattern,s)
  </code></pre>
  
  <p>it returns none.</p>
  
  <p>I tried taking the brackets off,</p>
  
  <pre><code>pattern='\s\d{11}/\d{8}' 
  </code></pre>
  
  <p>It still returns <code>none</code>. </p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>Why the re.match does not find anything? </li>
  <li>What is the difference with or without bracket in pattern?</li>
  </ol>
