Building a Python WeChat Message Sender with itchat and PyInstaller

This guide provides step‑by‑step instructions for creating a WeChat message‑spamming tool using Python.

1. Environment preparation

Install Python 3.6, then add the required third‑party libraries:

<code>pip install itchat</code>

<code>pip install pyinstaller</code>

2. Core code

<code>import itchat</code><code>import time</code><code>print("请扫描弹出的扫二维码")</code><code>itchat.auto_login(hotReload=True)</code><code>boom_name = input("请输入想发送的人：")</code><code>message = input("请输入发送的内容：")</code><code>number = int(input("请输入发送的次数："))</code><code>boom_obj = itchat.search_friends(remarkName=boom_name)[0]['UserName']</code><code>for i in range(1, number+1):</code><code>    time.sleep(0.01)</code><code>    print("正在发送第%d遍" % i)</code><code>    itchat.send_msg(msg=message, toUserName=boom_obj)</code>

3. Packaging the project into an executable

Use PyInstaller to create a single‑file executable:

<code>pyinstaller -F wechat.py</code>

After the build finishes, the executable appears in the dist directory. Running it will launch the script, prompting for the target contact, message content, and repeat count, then automatically send the messages via WeChat.
