And that would be totally silly and uncalled for -- why ever would it be placed *outside the current function*?! What a straw-man...! Just do def last_first(r): return r[0].lower(), r[5].lower() for k, g in groupby(iterable, key=last_first): ... putting the def right where you now have the "<name> = lambda ..." of course!
