title: setAttr of a list in maya python
body: <p>I'm still figuring out how Python and Maya work together so forgive ignorance on my part. So I'm trying to change the attributes of a list of joints in maya using a loop like so:</p>
  
  <p><code>for p in jointList: 
      cmd.getAttr(p, 'radius', .5)</code></p>
  
  <p>and I get this error:</p>
  
  <p><code>Invalid argument 1, '[u'joint1']'. Expected arguments of type (  list,  )</code></p>
  
  <p>I have no idea what I'm doing wrong.</p>
