【python】itchat登录微信获取好友签名并生成词云

在知乎上看到一篇关于如何使用itchat统计微信好友男女比例并使用plt生成柱状图以及获取微信好友签名并生成词云的文章https://zhuanlan.zhihu.com/p/36361397,感觉挺有意思,就照着学习了下,发现原文章中没有写明使用的库如何安装和使用到的资源没有说明,在这里详细的记录下。

本节用到的的库以及安装

itchat      

微信相关操作,cmd中‘pip install itchat’

pillow(pil)    

Image用到,cmd中‘pip install pillow’

re       

正则表达式

wordcloud    

词云,使用pip安装一直提示Built时候一直错误,所以在https://www.lfd.uci.edu/~gohlke/pythonlibs/中找到wordcloud对应版本,然后‘pip install wheel路径\*.whl’

jieba

分词库,可以对字符串中的词进行拆分,cmd中‘pip install jieba’

numpy

plt用到,cmd中‘pip install numpy’

引用库

 1 #!/user/bin/python
 2 ##coding=utf-8
 3 import itchat
 4 from itchat.content import *
 5 import numpy as np
 6 from matplotlib import pyplot as plt
 7 import re
 8 from wordcloud import WordCloud
 9 from wordcloud import ImageColorGenerator
10 import os
11 import io
12 import jieba
13 from PIL import Image

登录微信获取好友男女比例

 1 itchat.login()
 2 text=dict()
 3 friends = itchat.get_friends(update=True)[0:]
 4 male="male"
 5 female="female"
 6 other="other"
 7 for i in friends[1:]:
 8     sex = i['Sex']
 9     if sex == 1:
10         text[male] = text.get(male, 0) + 1
11     elif sex == 2:
12         text[female] = text.get(female, 0) + 1
13     else:
14         text[other] = text.get(other, 0) + 1
15 total = len(friends[1:])
16 print(total)
17 print("男性好友: %.2f%%" %(float(text[male]) / total * 100)+"\n" + 
18     "女性好友:  %.2f%%" %(float(text[female]) / total * 100) + "\n" +
19     "不明性别好友: %.2f%%" %(float(text[other]) / total * 100))

使用PLT柱状图绘制男女比例

1 def draw(datas):
2     for key in datas.keys():
3         plt.bar(key,datas[key])
4 
5     plt.legend()
6     plt.xlabel('sex')
7     plt.ylabel('rate')
8     plt.title("Gender of Alfred's friends")
9     plt.show()

爬取好友签名并保存到文件

 1 def parse_signature():
 2     itchat.login()
 3     siglist = []
 4     friends = itchat.get_friends(update=True)[1:]
 5     for i in  friends:
 6         signature = i["Signature"].strip().replace("span","").replace("class","").replace("emoji","")
 7         rep = re.compile("lf\d+\w|[<>/=]")
 8         signature = rep.sub("",signature)
 9         siglist.append(signature)
10     text = "".join(siglist)
11     with io.open('text.txt', 'a', encoding='utf-8') as f:
12         wordlist = jieba.cut(text, cut_all=True)
13         word_space_split = " ".join(wordlist)
14         f.write(word_space_split)
15         f.close()

解析文件并绘制词云

准备一张图片(8.jpg)放到当前目录下,字体资源准备好(DroidSansFallbackFull.ttf),可以使用everything搜索一下自己电脑中的字体资源拿过来一个用,放到当前目录下,如果没有会提示资源的问题。

1 def draw_signature():
2     text = open(u'text.txt', encoding='utf-8').read()
3     coloring = np.array(Image.open('8.jpg'))
4     my_wordcloud = WordCloud(background_color="white", max_words=2000,mask=coloring, max_font_size=300,random_state=42,scale=2,font_path="DroidSansFallbackFull.ttf").generate(text)
5     image_colors = ImageColorGenerator(coloring)
6     plt.imshow(my_wordcloud.recolor(color_func=image_colors))
7     plt.imshow(my_wordcloud)
8     plt.axis("off")
9     plt.show()

小插曲:微信自动回复

 1 @itchat.msg_register([PICTURE,TEXT])
 2 def simple_reply(msg):
 3     if msg['Type'] == TEXT:
 4         ReplyContent = 'I received message: '+msg['Content']
 5     if msg['Type'] == PICTURE:
 6         ReplyContent = 'I received picture: '+msg['FileName']
 7     itchat.send_msg('nice to meet you',msg['FromUserName'])
 8 
 9 itchat.auto_login()
10 itchat.run()
