determining the bounds of a tuple returned from a database

[ronrsr]

very sorry, that was my error - len(result[0]) and len(result[1]) both
return 1 --

i think I'm misunderstanding what len() does - to me they appear to
have 2 or 3 elements, or at least be composed of a string of some
length.

I guess len() isn't the function i'm looking for then.  How do I tell
how many strings, or how many bytes are in each dimension?  so that I
can iterate through them.

Each entry in that list is a keyword - Alternately, is there any fast
way to parse that into a sorted list of distinct keywords.

very sorry for the error.

bests,
