本文介绍如何使用Python从微信好友的个性签名中提取文本，并利用jieba分词及WordCloud生成个性化词云图。文章提供了完整的代码实现，包括安装所需库、获取个性签名、处理文本、生成词云图等步骤。

1. 安装

pip3 install wordcloud

如果报错

下载对应的whl文件https://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud

进入whl所在的目录

用pip3 命令安装例：pip3 install xxxxxxxxx.whl

pip3 install Pillow

pip3 install jieba

pip3 install itchat

2. 获取微信好友的个性签名

TList = []
def get_signature():
    friends = itchat.get_friends(update=True)[0:]
    for friend in friends:
        signature = friend["Signature"].strip()
        signature = re.sub("<span.*>", "", signature)
        signature = re.sub(" ", "", signature)
        signature = re.sub("emoji ", "", signature)
        TList.append(signature)

3. 生成云图片

首先要将想要生成云图片形状的模板图片放在当前目录下

def cloud_pic():
    raw_signature_string = ''.join(TList)
    text = jieba.cut(raw_signature_string, cut_all=True)
    wl_space_split = ' '.join(text)

    d = os.path.dirname(os.path.abspath(__file__))

    alice_coloring = np.array(Image.open(os.path.join(d, "dm.jpg"))) #原图

    my_wordcloud = WordCloud(background_color="white", #背景色
            max_words=2000,    #字数上限
            mask=alice_coloring, #形状
            max_font_size=50,#字体大小
            random_state=150, #随机数量
            font_path='C:/Windows/Fonts/simhei.ttf').generate(wl_space_split) #中文字体
    image_color = ImageColorGenerator(alice_coloring)
    plt.imshow(my_wordcloud.recolor(color_func=image_color))
    plt.imshow(my_wordcloud)
    plt.axis("off")
    plt.show()

PS:如果要生成中文云词，则要用中文字体，否则生成的是矩形框

4. 结果

原图	生成图
