title: python 'int' object has no attribute 'sort'
body: <p>Hey I am new to Python and I have this exercise I want to complete but I get the following error: 'int' object has no attribute 'sort'. 
   I must use for-loop to take from a list of numbers and make them all square, then print them all out one by one as sorted. 
   Did I use the sort command incorrectly? Or it doesen't even work with numbers? And do I have to use the .append() command to make them all print out one by one?
  So this is my wannabe code so far:</p>
  
  <pre><code>start_list = [5, 3, 1, 2, 4]
  square_list = []
  for square_list in start_list:
      square_list ** 2
  print square_list.sort()
  </code></pre>
