Check out some sayings online:

1. openpyxlThe function used saveto save the data in Excela file.
2. In the case that the save is not completed, load_workbookthe function is used to load the Excelfile.

  Solution: Do not use the function before executing the save function to save the data load_workbook.

My workaround: 

But I didn't write the Excel file, let alone save it, so this solution doesn't apply to my problem. Later, when I manually opened the Excel file, I found that it could not be opened. I found that the file was encrypted and locked, and I did not have permission to read the file. After removing the encryption lock of the file, the problem was solved.
