How do I get a slice of a string held in a tuple?

The only difference is that in the "workaround that works" you're
mungling mydata[1], in the "bad code" mydata[0].  If you print or
otherwise emit the value of index in each case, I think the cause of
your problem will become clear (and it will probably be a value of index
that's -1 for the "failing" case, and >= 0 for the "working" case, as
other posts on this thread have already suggested).

No connection can exist between your problem, and the string being "held
in a tuple" or held in any other fashion.
