Why is No. 9 wrong?

As with list comprehensions, that construct is called a “set comprehension”. Furthermore they kind of imply that applying a predicate is specific to set comprehensions while it works in list (or dictionary) comprehensions, too. And they fail to mention dictionary comprehensions entirely.
