In your code, index = () means it is a tuple. IIRC, it should be a
dictionary. For that, index = {}. This is the one causing the following
error in your code,

  if not index.has_key(value):
AttributeError: 'tuple' object has no attribute 'has_key'

You can not use has_key over a tuple object.

But where is the "indentation error" ? I see nothing like that in the error
message.
