title: Looping through python function arguments
body: <p>I have a python function that receives many arguements. I want to change all the functions arguements to lowercase.
  I have this code:</p>
  
  <pre><code>functionOne(para, paraa, parab):
      arguments = locals()
      print arguments
      for keys in arguments:
         arguments[keys] = str(arguments[keys]).lower()
         print arguments[keys]
      print para
  </code></pre>
  
  <p>With the output:</p>
  
  <pre><code>{'para':'HP', 'paraa':'MA', 'parab':'aM'}
  hp
  ma
  am
  HP
  </code></pre>
  
  <p>I would like para to equal hp not HP.</p>
