title: Python regex match middle of string
body: <p>I have a python string, that I'm trying to extract. I have a interesting issue:</p>
  
  <pre><code>&gt;&gt;&gt; s="SKU 9780136058281, (ASIN B00A2KNZ2S, (binding Merchant: 'paperback' / 'hardcover'))"
  &gt;&gt;&gt; print(re.match('ASIN', s))
  None
  &gt;&gt;&gt; print(re.match('SKU', s))
  &lt;_sre.SRE_Match object; span=(0, 3), match='SKU'&gt;
  </code></pre>
  
  <p>I'm trying to mach a the number after ASIN. I can't still see a obvious problem.  Its matching the beginning of the line, but not in the middle. </p>
