I don't think it's clever, it's quite unintuitive and ugly. To me anyway. If the author really wanted to cram everything into a list comprehension, the logical way to think about it is:

    (
        (int(tsc, 16), int(pc, 16))
        for tsc, _, pc, *_ in (line.strip().split(",") for line in fp)
    ),

Which is, of course, almost as ugly. Just use a for loop and yield

Right, I should have said clever code golf.

I think I would have written it like that:

    def parse(line):
      p = line.split(",")
      return ((int(p[0], 16), int(p[2], 16))
    (parse(line)) for line in fp)

And when it was still cool: map(parse, fp)
