Openpyxl: “permission denied” but Excel sheet not open

问题

I have a piece of code I've been using successfully for quite a while. There is a piece of it that loops through a small list of employees and writes each of their top 20 products to an Excel sheet. Now it is often (but not always) throwing an error: (see below for full traceback)

PermissionError: [Errno 13] Permission denied:

I.e., the error you'd get if you accidentally had the spreadsheet open when running the code. This is not the case now. Here's the relevant code:

for e in employee_list:
    df4 = e
    df4 = pd.DataFrame()
    df4 = df4.append(df3.loc[df3['Employee'] == e], sort = False)

    book = load_workbook(filename)
    sheet = e + '_qtr'
    writer = pd.ExcelWriter(filename, engine='openpyxl')
    writer.book = book
    writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
    df4.to_excel (writer, sheet)
    writer.save()

A thought I had was perhaps the code is running faster now? I made some minor changes to the code meant to streamline it before this error started happening. Could it be that OpenPyXL is still working on saving when the loop comes back around?

Any help is appreciated!

I figured it out. Microsoft Onedrive was trying to upload the file to the cloud while I was working with it. I've changed those settings and now it works fine!
