That was a mistake, I intended to write re.search().group(1), not re.finditer().group(1). I clarified this in another reply to the thread about an hour ago. Sorry for the confusion, I wrote the reply after being up for a while and got re.findter() and re.search() mixed up in my head. You're correct.
