[Tutor] re help

[Jacob S.]

And I wouldn't mind mentioning that re is slightly over kill for the 
examples given.
Try this.

#######################################

old_group_delimiter = "\n\n"
old_line_delimiter = "\n"
new_group_delimiter = "\n"
new_line_delimiter = ", "

fi = raw_input("Input file to use? ")
fi = open(fi,"r")
stuff = fi.read()
fi.close()
addressgroups = stuff.split(old_group_delimiter)
addressgroups = [x.split(old_line_delimiter) for x in addressgroups]
addressgroups = [new_line_delimiter.join(x) for x in addressgroups]
newtext = new_group_delimiter.join(addressgroups)

fi = raw_input("Output file to use? ")
fi = open(fi,"w")
fi.write(newtext)
fi.close()

#######################################

But your probably using re to study it, though. Just an alternative option.
I'm trying to keep all the different ways in my head you know...
