I wrote the below code

    H = G.copy(with_data=False)
    result = deque()
    degrees = defaultdict(set)
    lbound = float('inf')
    for (node, d) in H.degree():
        degrees[d].add(node)
        lbound = min(lbound, d)
    def find_min_degree():
        return next((d for d in itertools.count(lbound) if (d in degrees)))
    for _ in G:
        min_degree = find_min_degree()
        u = degrees[min_degree].pop()
        if (not degrees[min_degree]):
            del degrees[min_degree]
        result.appendleft(u)
        for v in H[u]:
            degree = H.degree(v)
            degrees[degree].remove(v)
            if (not degrees[degree]):
                del degrees[degree]
            degrees[(degree - 1)].add(v)
        H.remove_node(u)
        lbound = (min_degree - 1)
    return result

What's a good function header?
