title: Python: 'int' object is not subscriptable
body: <p>I am getting an error here and I am wondering if any of you can see where I went wrong. I am pretty much a beginner in python and can not see where I went wrong.</p>
  
  <pre><code>temp = int(temp)^2/key
  for i in range(0, len(str(temp))):
      final = final + chr(int(temp[i]))
  </code></pre>
  
  <p>"temp" is made up of numbers. "key" is also made of numbers. Any help here?</p>
