But test() returns [1, 2]. So does that say (as you claim above) that "the comprehension ran in the enclosing scope"? Doesn't it just say that the outermost iterable runs in the enclosing scope?

Yes - because the outermost iterable runs in the enclosing scope. But suppose you worded it like this:

def test(): a = 1 b = 2 vars = {key: locals()[key] for key in locals()} return vars

What would your intuition say? Should this be equivalent to dict(locals()) ?
