title: Sorting elements in string with Python
body: <p>I need to sort string, and I came up with the following function.</p>
  
  <pre>
  def mysort(comb_): 
      str = [] 
      size = len(comb_) 
      for c in comb_: 
          str.append(c) 
      str.sort() 
      return ''.join(str) 
  </pre>
  
  <p>Is there any way to make it compact?</p>
