Ich bin neither a programmer nor do I understand the Python development language. I purely out of interest looked at materials in this area and wrote a simple introductory guide. I hope to throw out a brick to attract jade, and look forward to continuously seeing more excellent Python plugins appear in the future.

Resources:

1. The official development documentation is very good as an introduction. This article is based on this.

2. Sample programs provided officially—everything still depends on reading the code, this is the best learning method.
