How about:

a, b, c = readline(f)

You'd still need to solve that, one way or another. But the Pythonic
way is to distinguish between "input" and "output" parameters by
having the input parameters as parameters, and the output parameters
as the return value. And personally, I find it *way* more readable
that way; while it's perfectly possible to pass a list as a parameter
and have the function append to it, it's much clearer if your return
values are on the left of the equals sign.
