You need to learn how to solve problems as well as learning Python --
they go hand in hand -- but Python is a good language to get started
with.

That would require quite a long essay!  As to the question, it's a bit
odd to talk of opposites, but it's not ambiguous.  More problematic is
what to do with duplicates.  The question should be worded so that it's
either clear what is wanted, or so that it is clear that you should
decide what to do.
