    keys.append(v[0])
fr.close()
# 输出前几个的键值对
print("人物出现次数TOP", mainTop)
print(list(dic.items())[:mainTop])

# 　绘图
# 人名列表 (用于人物关系图,pyecharts人物出场次数图)
list_name = list(dic.keys())  # 人名
list_name_times = list(dic.values())  # 提取字典里的数据作为绘图数据


# 可视化人物出场次数
def creat_people_view():
    bar = Bar()
    bar.add_xaxis(list_name[0:keshihuaTop])
    bar.add_yaxis("人物出场次数", list_name_times)
    bar.set_global_opts(title_opts=opts.TitleOpts(title="人物出场次数可视化图", subtitle="三国人物TOP10"),
                        xaxis_opts=opts.AxisOpts(axislabel_opts={"rotate": 45}))
    bar.set_series_opts(label_opts=opts.LabelOpts(position="top"))
    # bar.render_notebook()  # 在 notebook 中展示
    # make_snapshot(snapshot, bar.render(), "bar.png")
    # 生成 html 文件
    bar.render("output/三国演义人物出场次数可视化图.html")

3.生成云词

# 生成词云
def creat_wordcloud():
    bg_pic = imageio.imread('prepare/bird.png')
    wc = wordcloud.WordCloud(font_path='c:\Windows\Fonts\simhei.ttf',
                             background_color='white',
                             width=1000, height=800,
                             stopwords=excludes,# 设置停用词
                             max_words=500,
                             mask=bg_pic  # mask参数设置词云形状
                             )
    # 从单词和频率创建词云
    wc.generate_from_frequencies(counts2)
    # generate(text)  根据文本生成词云
    # wc.generate(txt)
    # 保存图片
    wc.to_file('output/三国演义词云_人名.png')

    #  显示词云图片
    plt.imshow(wc)
    plt.axis('off')
    plt.show()


# 使用pyecharts 的方法生成词云
def creat_wordcloud_pyecharts():
    wordsAndTimes = list(dic.items())
    (
        WordCloud()
            .add(series_name="人物次数", data_pair=wordsAndTimes,
                 word_size_range=[20, 100], textstyle_opts=opts.TextStyleOpts(font_family="cursive"), )
            .set_global_opts(title_opts=opts.TitleOpts(title="三国演义词云"))
            .render("output/三国演义词云_人名.html")
    )

# 颜色生成
colorNum = len(list_name[0:peopleTop])

# print('颜色数',colorNum)
def randomcolor():
    colorArr = ['1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F']

    return "#" + color

def color_list():
    colorList = []
    for i in range(colorNum):
        colorList.append(randomcolor())
    return colorList

# 解决中文乱码
plt.rcParams['font.sans-serif'] = ['SimHei']  # 用来正常显示中文标签

4.生成人物关系图

# 生成人物关系图
def creat_relationship():
    # 人物节点颜色
    colors = color_list()
    Names = list_name[0:peopleTop]
    relations = {}
    # 按段落划分，假设在同一段落中出现的人物具有共现关系
    lst_para = (txt).split('\n')  # lst_para是每一段
    for text in lst_para:
        for name_0 in Names:
            if name_0 in text:
                for name_1 in Names:
                    if name_1 in text and name_0 != name_1 and (name_1, name_0) not in relations:
                        relations[(name_0, name_1)] = relations.get((name_0, name_1), 0) + 1
    maxRela = max([v for k, v in relations.items()])
    relations = {k: v / maxRela for k, v in relations.items()}
    # return relations

    plt.figure(figsize=(15, 15))
    # 创建无多重边无向图
    G = nx.Graph()
    for k, v in relations.items():
        G.add_edge(k[0], k[1], weight=v)
    # 筛选权重大于0.6的边
    elarge = [(u, v) for (u, v, d) in G.edges(data=True) if d['weight'] > 0.6]
    # 筛选权重大于0.3小于0.6的边
    emidle = [(u, v) for (u, v, d) in G.edges(data=True) if (d['weight'] > 0.3) & (d['weight'] <= 0.6)]
    # 筛选权重小于0.3的边
    esmall = [(u, v) for (u, v, d) in G.edges(data=True) if d['weight'] <= 0.3]
    # 设置图形布局
    pos = nx.spring_layout(G)  # 用Fruchterman-Reingold算法排列节点（样子类似多中心放射状）
    # 设置节点样式
    nx.draw_networkx_nodes(G, pos, alpha=0.8, node_size=1300, node_color=colors)
    # 设置大于0.6的边的样式
    nx.draw_networkx_edges(G, pos, edgelist=elarge, width=2.5, alpha=0.9, edge_color='g')
    # 0.3~0.6
    nx.draw_networkx_edges(G, pos, edgelist=emidle, width=1.5, alpha=0.6, edge_color='y')
    # <0.3
    nx.draw_networkx_edges(G, pos, edgelist=esmall, width=1, alpha=0.4, edge_color='b', style='dashed')
    nx.draw_networkx_labels(G, pos, font_size=14)

    plt.title("《三国演义》主要人物社交关系网络图")
    # 关闭坐标轴
    plt.axis('off')

    # 保存图表
    plt.savefig('output/《三国演义》主要人物社交关系网络图.png', bbox_inches='tight')
    plt.show()


def main():

    #生成词频词性文件
    create_wordproperties()
    # 人物出场次数可视化图
    creat_people_view()

    # 词云图
    creat_wordcloud()
    creat_wordcloud_pyecharts()
    # 人物关系图
    creat_relationship()

if __name__ == '__main__':
    main()

3.运行结果截图

1.统计词频词性并写入文件中

2.可视化人物出现次数

3.生成云词

4.生成人物关系图
