In your comprehension example, I'm fairly certain the filtering should be on
the post incremented remainder
[ x+1 for x in [1,2,3] if (x+1) % 2 == 0]
I think that is the downside of the comprehension, having to repeat that twice.
Maybe you can get around it with := ?? I'm stuck on 3.7 so I don't know for
sure.
