| Is it? I think I've learned more about Python than Jim has (already finished

He may have gauged better than I the original poster's zeal for
discovering things on his own, but I was surprised no one mentioned
string.join'ing a list of fields in one step.  It's what I consider
the normal approach to this common task.  Easier on the eyes, probably
faster if there are more than a couple of fields.

  fields = []
  ...
  fields.append(last_field)
  delimitedString = string.join(fields, ',')

Might apply in the poster's situation, hard to say how well.
