如何寫入現有的Excel文件（XLS）

Question

我是新手。我嘗試在現有的Excel文件中寫入數據。當我在robotframework上運行時，它顯示「沒有關鍵字與名稱」寫入Excel文件「找到」。那麼你能幫我解決我的代碼或給我一些建議嗎？

import xlwt 
from xlutils.copy import copy 

class Excel(object): 

    def __init__(self): 
     print "write to excel file" 

    def group(self,lst, n): 

     return ([lst[i:i+n] for i in range(0,len(lst),n)]) 
    def write_to_excel_file(self,filename,content_list): 

      # Existing Excel File 
      w = copy(filename) 
      b = w.get_sheet(0) 

      # Create an new Excel file and add a worksheet. 
      #workbook = xlwt.Workbook() 
      #worksheet = workbook.add_sheet('wb') 

      #content_lists=[1,1,'hello',2,1,'brother',3,1,'how are you',4,1,'are you good today'] 
      t=self.group(content_list,3) 
      #print(t) 
      for item in t: 
       b.write(int(item[0]), int(item[1]), item[2]) 


      # close work book 
       w.save(filename)
