我正在嘗試在 excel 文件 (xls) 中使用搜索和替換字符串，實際上 - 我需要查找字符串并在前綴 * 之前添加。例如但我收到一個錯誤：LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced}NameError: name 'two_replaced' is not defined代碼：from xlrd import open_workbookfrom xlutils.copy import copyimport xlsxwriterrb = open_workbook("template.xlsx")# Create an new Excel file and add a worksheet.wb = xlsxwriter.Workbook('Updated_Workbook1.xlsx')ws = wb.add_worksheet()s_orig = rb.sheet_by_index(0)LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced,}for row in range(s_orig.nrows):    for col in range(s_orig.ncols):        if s_orig.cell(row,col).value in LVdemact:            # s.write(row, col, LVdemact[item])            ws.write(row, col, LVdemact[s_orig.cell(row,col).value])        else:            ws.write(row, col, s_orig.cell(row,col).value)wb.close()
