Why don't you use sets instead of lists ? It would make your life much easier.

Specifically here, the problem seems to be that for some s there is more than 
one substring of it that fails to be in prunedK, so that the failing line is 
called more than once for a single s.

The simplest modification is to replace your first 'continue' by a 'break' (and 
remove the second 'continue' which serves no purpose).
