title: Matching whole words using "in" in python
body: <p>I've been searching around for some time for this, but have still not found an answer, maybe its got some thing to do with regular expressions, but i think there should be a simple answer that I am missing here. It seems very trivial to me ... here goes:</p>
  
  <p>On the python interpreter I get:</p>
  
  <pre><code>"abc" in "abc123" 
  </code></pre>
  
  <p>as True. </p>
  
  <p>I want it a command that returns a False. I want the entire word to be matched.</p>
  
  <p>Thanks!</p>
