title: Fastest way to classify surnames in python
body: <p>I have a list with 12K asian surnames from a census and a list with 200K names. I'd like to classify those 200K people as asians or non-asians based on wether their surname appears on my 12K list.</p>
  
  <p>Is there a fast way to verify if one of the elemenst in the list contains one of the surnames in the 12K list?</p>
