title: Why does Python remove the last character of a string?
body: <p>For example, if I do this <code>str(bin(66))</code> I get <code>0b1000010</code>, but if I do this <code>str(bin(66)).strip("0b")</code>, I get <code>100001</code> (notice the missing '0').</p>
  
  <p>I think I'm misusing the strip function.</p>
