I think that adding parentheses would help, by at least signalling that the logic is longer than just the next (single) expression.

level = (0 if "absoluteimport" in self.futures else -1)

Contrast with the bleeding obvious: level = 0 if "absoluteimport" in self.futures: level = -1 or even, if a certain obscurity is desirable: level = - ("absoluteimport" in self.futures) Wait a second. I may be just a user but if the above is correct then that syntax needs to die! There is no logical reason for "XX if YY else ZZ" to be roughly equivlent to: "if (YY) then {ZZ} else {XX}" , but AFAICT that is pretty much the way you expanded that. I hope I misunderstood, or that there was a typo in a post. There was a typo in the post.
