Welcome to the 13th issue of Python Trending Weekly, a weekly newsletter about Python, AI and general programming techniques. The original version of the weekly publication was written in Chinese, and what you are reading here is the English version translated by ChatGPT.
Most of the content shared here is in English, with a small portion in Chinese, which is indicated in the title. It took a lot of courage for me to publish this weekly publication, originally intended for Chinese readers, to the English-speaking world. Your feedback is welcome, and I appreciate your subscription and support!
