2019-06-02 Python之微信好友数据分析以及运用Pyecharts可视化

一.库的使用说明

pass

二.微信好友信息的获取

    def get_friends_info(self): #获取好像信息，返回lis列表
        bot = Bot()
        lis = [['name', 'real_name', 'sex', 'city', 'province']]  # 把信息存储为一个二维列表,添加头部信息
        friend_all = bot.friends()

        for a_friend in friend_all:
            NickName = a_friend.raw.get('NickName', None) #获取所有好友信息 raw表示获取全部信息
            RemarkName = a_friend.raw.get('RemarkName', None)
            Sex = {1: "男", 2: "女", 0: "其他"}.get(a_friend.raw.get('Sex', None), None)
            City = a_friend.raw.get('City', None)
            Province = a_friend.raw.get('Province', None)
            Signature = a_friend.raw.get('Signature', None)
            #HeadImgUrl = a_friend.raw.get('HeadImgUrl', None)
            #HeadImgFlag = a_friend.raw.get('HeadImgFlag', None)
            list_0 = [NickName, RemarkName, Sex, City, Province, Signature]
            lis.append(list_0)
        return lis

三.信息写入到excel

    def friends_info_lis_to_excle(self):
        import openpyxl
        lis = self.get_friends_info()
        wb = openpyxl.Workbook()
        sheet = wb.active
        sheet.title = self.sheetname
        for i in range(0, len(lis)):
            for j in range(0, len(lis[i])):
                sheet.cell(row=i+1, column=j+1, value=str(lis[i][j]))
        wb.save(self.filename)
        print("excel保存成功")

四.词云 注意，1要在当前py文件夹下面放一张名字为love 的jpg图片

　　　　　　  2 如果报错，可能是电脑缺少字体，可以改为msyh.ttc

 def city_wordcloud(self, save_name, condition):
        wordlist, giveup = self.extract_data_as_two_lis(condition)
        new_wordlist = list()
        for i in range(25):
            new_wordlist.append(wordlist[i])
        wl = ' '.join(wordlist)  # 把列表转换成str wl为str类型，所以需要转换
        cloud_mask = np.array(Image.open("love.jpg"))  # 词云的背景图，需要颜色区分度高
        wc = WordCloud(
            background_color="black",  # 背景颜色
            mask=cloud_mask,  # 背景图cloud_mask
            max_words=100,  # 最大词语数目
            font_path='simsun.ttf',  # 调用font里的simsun.tff字体，需要提前安装
            height=500,  # 设置高度
            width=2600,  # 设置宽度
            max_font_size=1000,  # 最大字体号
            random_state=1000,  # 设置随机生成状态，即有多少种配色方案
        )
        myword = wc.generate(wl)  # 用 wl的词语 生成词云
        # 展示词云图
        plt.imshow(myword)
        plt.axis("off")
        #plt.show()
        try:
            wc.to_file(save_name + '.jpg')  # 把词云保存下当前目录（与此py文件目录相同）
        except:
            print("词云保存失败")

五.地图可视化

#参数为condition,picture_name, keylist, valueslist, Map_condition->china或者广东创建html地图图片,图片名字为picture_name
    def map_picture(self, condition, picture_name, keylist, valueslist, Map_condition):
        from pyecharts import options as opts
        from pyecharts.charts import Map

        def map_visualmap() -> Map:
            new_keylist = list()
            new_valueslist = list()
            if condition == 'city':
                for i in range(len(keylist)):
                    # 列表处理,默认elsx里面的city没有'市'字，地图需要市字
                    new_keylist.append(keylist[i] + '市')
                    new_valueslist.append(valueslist[i])
            else:
                for i in range(len(keylist)):
                    new_keylist.append(keylist[i])
                    new_valueslist.append(valueslist[i])

            c = (
                Map()
                    .add("好友地图分布", [list(z) for z in zip(new_keylist, new_valueslist)], Map_condition)
                    .set_global_opts(
                    title_opts=opts.TitleOpts(title="Map-VisualMap"),
                    visualmap_opts=opts.VisualMapOpts(max_=100),
                )
            )
            try:
                c.render(picture_name)
            except:
                print("html地图图片创建失败")
            print('html地图图片保存成功')
        map_visualmap()#调用自己
