Python：有没有办法在 1 个循环中写入 Excel 单元格并导出 PDF

Question

我的项目确实遇到了棘手的情况。我正在尝试更新 Excel Sheet 并在一个循环中将其导出为 PDF。目前我认为最好的是 openpyxl 库。问题是写入和打印功能都以不同的方式打开 Excel.. 使用：

book = openpyxl.load_workbook(excel_file) 和 wb = excel.Workbooks.Open(excel_file).

这两个功能相互交叉并产生权限问题（至少它看起来像）加上崩溃的 Jupyter :)。

请问有什么优雅的方法可以做到这一点，或者我真的需要 2 个循环？

错误调用示例： PermissionError：[Errno 13] 权限被拒绝：'C:/Users/admin/test_files/dir#$$.xlsx'

代码如下所示：

def update_directory():


excel_file = r'C:/Users/admin/test_files/doo.xlsx'

excel = client.DispatchEx("Excel.Application")
excel.Visible = 0

folder_selected = filedialog.askdirectory()
os.chdir(folder_selected)


for root, dirs, files in os.walk(".", topdown=False):
    
    for name in dirs:
                                               
        a_pth = os.getcwd()
        pdf_file = os.path.join(a_pth,name," ")+"Dic_"+"%s.pdf" % name
            
        book = openpyxl.load_workbook(excel_file)
        sheet= book['Sheet1']
        sheet.cell(row=4, column=6).value = name
            
        book.save(excel_file)
            
        wb = excel.Workbooks.Open(excel_file)
        ws = wb.Worksheets[1]
         
        ws.SaveAs(pdf_file, FileFormat=57)
            
            
wb.Close() # <- need to be part of loop (comment from Amiga500). File save 
           #    prompt from Excell present. 
excel.Exit()

有条目

wb.application.displayalerts = False

刚好在

之前插入

wb.Close()

行似乎对我有用，所以代码片段类似于

    book = openpyxl.load_workbook(excel_file)
    sheet= book['Sheet1']
    sheet.cell(row=4, column=6).value = name
        
    book.save(excel_file)
        
    wb = excel.Workbooks.Open(excel_file)
    ws = wb.Worksheets[1]
     
    ws.SaveAs(pdf_file, FileFormat=57)
    
    wb.application.displayalerts = False  #This stops the popup asking for a save
    wb.Close() # <- need to be part of loop (comment from Amiga500). File save 
       #    prompt from Excell present.

注意 wb.Close() 与内部 for 循环的其余部分缩进相同。
