Python Itchat Automation and Packaging with PyInstaller: Step‑by‑Step Guide
This tutorial explains how to set up a Python environment, install the itchat and pyinstaller libraries, write a script that logs in via QR code to send repeated messages to a chosen contact, and finally package the script into a standalone executable using PyInstaller.
First, set up the Python environment by installing the required third‑party libraries itchat and pyinstaller using pip install itchat and pip install pyinstaller .
Next, the core script imports itchat and time, logs in via QR code, prompts the user for the target friend, message content, and repeat count, then sends the message in a loop with a short delay.
The script can be packaged into a standalone executable with PyInstaller; using the pyinstaller -F wechat.py command creates a single .exe file in the dist folder. Optional flags such as -w (windowed) and -i (icon) customize the build.
After building, run the generated executable to launch the QR‑code login and send messages as specified.
