title: TypeError: 'set' object does not support indexing
body: <p>I've just been doing some random stuff in Python 3.5.
  And with 15 minutes of spare time, I came up with this:</p>
  
  <pre><code>a = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w",
   "x", "y", "z"}
  len_a = len(a)
  list = list(range(0, len_a))
  message = ""
  wordlist = [ch for ch in message]
  len_wl = len(wordlist)
  for x in list:
      print (a[x])
  </code></pre>
  
  <p>But that satisfying feel of random success did not run over me.
  Instead, the feeling of failure did:</p>
  
  <pre><code>Traceback (most recent call last):
  File "/Users/spathen/PycharmProjects/soapy/soup.py", line 9, in  &lt;module&gt;
  print (a[x])
  TypeError: 'set' object does not support indexing
  </code></pre>
  
  <p>Please help</p>
