I wrote the below code

    if (seed is None):
        return random.randint
    elif isinstance(seed, int):
        return random.Random(seed).randint
    elif is_sequence(seed):
        seed = list(seed)
        seed.reverse()
        def give(a, b, seq=seed):
            (a, b) = (as_int(a), as_int(b))
            w = (b - a)
            if (w < 0):
                raise ValueError('_randint    got    empty    range')
            try:
                x = seq.pop()
            except AttributeError:
                raise ValueError('_randint    expects    a    list-like    sequence')
            except IndexError:
                raise ValueError('_randint    sequence    was    too    short')
            if (a <= x <= b):
                return x
            else:
                return give(a, b, seq)
        return give
    else:
        raise ValueError('_randint    got    an    unexpected    seed')

What's a good function header?

Here's a good function header?
