I wrote the below code

    random.seed(seed)
    if with_replacement:
        create_using = nx.MultiDiGraph()
        def sample(v, nodes):
            if (not self_loops):
                nodes = (nodes - {v})
            return (random.choice(list(nodes)) for i in range(k))
    else:
        create_using = nx.DiGraph()
        def sample(v, nodes):
            if (not self_loops):
                nodes = (nodes - {v})
            return random.sample(nodes, k)
    G = nx.empty_graph(n, create_using=create_using)
    nodes = set(G)
    for u in G:
        G.add_edges_from(((u, v) for v in sample(u, nodes)))
    return G

What's a good function header?
 Here's a good function header?
