ゝ一世哀愁。 2022-02-26 02:42 152阅读 0赞

本次涉及到的知识：

1.  itchat模块的使用
2.  pyecharts模块的使用
3.  jieba模块的使用
4.  PIL模块的使用

# python版本 #

python3.6

# 准备工作 #

## 1.安装itchat、pyecharts、jieba、pillow模块 ##

pip3 install itchat
    pip3 install pyecharts
    pip3 install jieba
    pip3 install pillow

## 2.阅读文档 ##

itchat模块可以实现登录微信，获取微信好友的信息等等功能。itchat文档：[https://itchat.readthedocs.io/zh/latest/api/][https_itchat.readthedocs.io_zh_latest_api]

pyecharts模块可以实现数据可视化，pyecharts文档：[http://pyecharts.org/\#/zh-cn/charts\_configure?id=xyaxis][http_pyecharts.org_zh-cn_charts_configure_id_xyaxis]

jieba模块可以实现中文分词，结巴分词文档：[https://github.com/fxsjy/jieba][https_github.com_fxsjy_jieba]

还需要在当前目录下创建三个文件才能正常运行：

head\_img：保存好友头像

img：保存可视化结果图片

html：保存可视化结果html文件

# 最终结果 #

### 1.好友性别比例 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hoeTExMDc3ODY4NzE_size_16_color_FFFFFF_t_70][]

程序员不愧是程序员，好友里面女生挺少的。

### 2.好友地理位置分布图 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hoeTExMDc3ODY4NzE_size_16_color_FFFFFF_t_70 1][]

才发现自己加了这么多地方的好友呀。

### 3.好友地理位置热力图 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hoeTExMDc3ODY4NzE_size_16_color_FFFFFF_t_70 2][]

由于我是居住在成都，因此成都的好友当然很多啦

### 4.好友签名词云 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hoeTExMDc3ODY4NzE_size_16_color_FFFFFF_t_70 3][]

努力、人生。。。加油吧骚年！！！

### 5.好友头像  ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hoeTExMDc3ODY4NzE_size_16_color_FFFFFF_t_70 4][]

哇哦。。。

关于怎样将所有微信好友的头像拼接成一张图片，可以参考[https://blog.csdn.net/Monster\_H7/article/details/80370204][https_blog.csdn.net_Monster_H7_article_details_80370204]

关于出现地理位置不匹配的错误，请下载我github项目里的city\_coordinates.json文件，并将其复制到$PYTHON\_HOMR\\Lib\\site-packages\\pyecharts\\datasets目录下。pyecharts自带的地理位置库真的坑，很多地方都匹配不到。

关于哈工大停用词文件，请到我的github下载。
