Unlock WeChat Automation with Python: From Login to Smart Auto‑Replies

0. itchat

We explored the open‑source itchat library (author @LittleCoder) that wraps the WeChat Web API, making it easy to log in, send messages, and retrieve data. pip install itchat Example to log in and send a message to the built‑in “filehelper”:

import itchat
itchat.login()
itchat.send(u'你好', 'filehelper')

1. Friend gender ratio

By fetching the friend list and counting the gender field we can compute the male‑female distribution. The result is shown in the screenshots below.

For a more visual presentation we can use echarts‑python to draw a pie chart.

pip install echarts-python

2. Signature word cloud

We retrieve each friend’s signature, clean emojis and other noise with regular expressions, then segment the text using jieba and generate a word cloud with wordcloud. Required packages:

pip install jieba
pip install wordcloud

After processing, the word cloud visualizes the most frequent words.

3. Automatic reply

Using a decorator we can listen for incoming messages of various types and reply automatically, while also forwarding the content to the filehelper for centralized viewing.

@itchat.msg_register(['Map', 'Card', 'Note', 'Sharing', 'Picture'])
def reply(msg):
    # handle message and send reply
    pass
