title: Comparing string and unicode in Python 2.7.5
body: <p>I wonder why when I make:</p>
  
  <pre><code>a = [u'k',u'ę',u'ą']
  </code></pre>
  
  <p>and then type:</p>
  
  <pre><code>'k' in a
  </code></pre>
  
  <p>I get <code>True</code>, while:</p>
  
  <pre><code>'ę' in a
  </code></pre>
  
  <p>will give me <code>False</code>?</p>
  
  <p>It really gives me headache and it seems someone made this on purpose to make people mad...</p>
