title: Encryption returns the same string as inputted original
body: <p>This program will encrypt a message. It will take all the values with an even numbered index and place it into a list, and leave the odds in the first list. In the end it will give you a post Transposition encryption
  message. 
  Example: ababab becomes aaabbb</p>
  
  <p>The above is what the program is supposed to do, however when I actually run the program the exact same string is given instead of the encrypted version.</p>
  
  <pre><code>crypt = [] # list to store original answers
  original = raw_input("Enter your string: ") # prompts user for their desired string
  crypt.append(original) # stores user answers in list crypt
  crypt2 = [] # all the items with an even index from list crypt
  x = 0
  
  for a in crypt:
     if x % 2 == 1: # checks for oddness in the index value
        crypt2.append(a) # adds value associated with index to list crypt2
        crypt.remove(a) # removes value associated with index from list crypt
     x += 1
  
  print crypt + crypt2
  </code></pre>
  
  <p>Is there an issue with the logic portion of my program?</p>
