Python_ how to operate the Excel file and rearrange the data.

I haven't written an article on CSDN for a long time, and now I am not just doing Unity, nor just staying in the initial stage of development. In addition to working for so long, Unity, UE4, Python, Flutter, Playcanvas, ThreeJS, etc. are all working on it. There are too many things, and the energy is not enough, so I will stop writing. I also thank CSDN, which is a great help on my program path!
In the future, I will work hard as a product manager.

Code purpose: Change the horizontal data structure in EXCLE to a vertical structure.
The code is pasted directly, and there are few explanations. The purpose of this article is mainly for personal records, which is convenient for pasting and use later. Please forgive me if there are any unsatisfactory places.

        # 附近我会放上已经处理好的数据，可以更方便了解做了什么。
