You don't say, but I assume you're using Python 2.x

Copy and paste the entire traceback please if you want help.  We have 
very little chance of working out what produced that error without it.

Which "b"?  Don't leave us guessing, we might guess wrong.

Really?  It looks to me like you are getting exactly what you asked for. 
  What format were you expecting?  What are you getting that doesn't 
belong.  I suspect that you don't want the "enumerate", but beyond that 
I have no idea what you're after.
