既存のExcelファイル（XLS）に書き込む方法

Question

私は初心者です。私は既存のExcelファイルにデータを書き込もうとします。 robotframeworkを実行すると、「No keyword with name 'Excelファイルに書き込む」というメッセージが表示されます。だから、私のコードを修正したり、私に提案してもらうことができますか？

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)

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

    def group(self,lst, size): 
     return ([lst[i:i+size] for i in range(0, len(lst), size)]) 

    def write_to_excel_file(self,filename,content_list): 
     if not os.path.exists(filename): 
      workbook = xlwt.Workbook() # Create an new Excel file and add a worksheet. 
      worksheet = workbook.add_sheet('wb') #add worksheet 
      workbook.save(filename) 
     rb = xlrd.open_workbook(filename,formatting_info=True) 
     r_sheet = rb.sheet_by_index(0) 
     r = r_sheet.nrows 
     wb = copy(rb) 
     sheet = wb.get_sheet(0) 
     t=self.group(content_list,3)
