title: ValueError: not enough values to unpack (expected 2, got 1) using list
body: <p>I'm trying to run this code below:</p>
  
  <pre><code>namelist =[[('mixamorig:Head', 'head')],
             [('mixamorig:Neck', 'neck_01')]]
  for name, newname in namelist:
      pb = obj.pose.bones.get(name)
      if pb is None:
          continue
      pb.name = newname
  </code></pre>
  
  <p>But it gives this error:</p>
  
  <pre><code>  for name, newname in namelist:
  ValueError: not enough values to unpack (expected 2, got 1)
  </code></pre>
  
  <p>I've tried to replace the <code>[</code> with <code>(</code> or add different enclosures but nothing worked, how can I fix this problem?</p>
