按照二元組的其中一個元素排序

    print('degree sequence',H.degree())
    H_degree_sequence = sorted(((n,d) for n, d in H.degree()), reverse=False)
    print('This is H_degree_sequence in function', H_degree_sequence)

H.degree()函式返回（node, degree)。在sorted語句中key為n, 對（n,d)進行了排序；

若改為如下程式碼，則變為key=d, 對（d,n)進行了排序；

    print('degree sequence',H.degree())
    H_degree_sequence = sorted(((d,n) for n, d in H.degree()), reverse=False)
    print('This is H_degree_sequence in function', H_degree_sequence)
