Combine multiple excel files with multiple sheets in sheet order

Combine multiple excel files with multiple sheets in sequence.

In business, when encountering multiple xlsx files containing sheets of the same name and in the same order under a folder, through python3, refer to (copy most of) the code:

https://www.cnblogs.com/zlhuan/p/8011304.html

In addition, there are pandas methods, and I will continue to learn to implement them later.

Implementation instructions:

• All xlsx files are placed in one folder, no other files.
• The python package is supplemented by itself.
• When entering the file name, it is not necessary to enter the suffix.
• An exe file that can be run under windows has been made, available for download
