Okay. The set example that I gave will work, then - as long as all
items are hashable (if they're strings, they are). Up to you which
one's more readable.

In any case, that could do with a supporting comment. My first
suspicion was that it ought to be written as:

fake_result = '[omitted]' not in fake_data

and that it was calculating the wrong thing. But it is doing what you
think it is.
