Actually, I'm closer to -1 on (a) as well. I don't like := as a way of getting assignment in an expression. The only thing I would give a non-negative rating is some form of "where" or "given".
+1 to this; ‘:=’ doesn't convey the meaning well. Python's syntax typically eschews cryptic punctuation in faviour of existing words that convey an appropriate meaning, and I agree with Greg that would be a better way to get this effect.
