python 3.7 实现 微信朋友信息统计

前提，已安装好python ，pycharm

安装依赖：
file -> setting ,依照下图添加依赖，

安装下面三个依赖库，
itchat
numpy
pyecharts

如果安装较慢的话，可以配置仓库，

https://pypi.tuna.tsinghua.edu.cn/simple
http://mirrors.aliyun.com/pypi/simple/
https://pypi.mirrors.ustc.edu.cn/simple/

全部代码都在下面，需要在下面
我的代码在itChatTest.py里，在同级目录新建img和result文件夹存放生成的文件

import itchat
import re
import csv
import os
import random
import numpy as np
import PIL.Image as Image
from collections import Counter
from pyecharts.charts import Bar, Pie, Map, WordCloud
from pyecharts import options as opts
