我尝试用下面的脚本将值写入excel文件(XLS)。 有4行值,但输出只显示1行。如何在excel(XLS)机器人框架中编写循环?

第二个问题:我可以使用现有的文件吗?

*** Settings *** 
Library   Collections 
Library   WriteExcel.Excel 

*** Variables *** 

*** Test Cases *** 
Write Excel Test 
    [Tags] 
    @{content} Create List 
    Append To List ${content} 1 1 Test Case 1 
    Append To List ${content} 2 1 Test Case 2 
    Append To List ${content} 3 1 Test Case 3 
    Append To List ${content} 4 1 Test Case 4 
    Write To Excel File test3.xls ${content} 

这是我WriteExcel.py

import xlwt 

class Excel(object): 

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

    def group(self,lst, n): 

     return zip(*[lst[i:n] for i in range(n)]) 
    def write_to_excel_file(self,filename,content_list): 

      # 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: 
       worksheet.write(int(item[0]), int(item[1]), item[2]) 


      # close work book 
       workbook.save(filename) 

This is my result

你't'只包含一个元组进行迭代/写入文件: '>>> MYLIST = [1,1,“测试1“,2,1,”测试2“,3,1,”测试3“,4,1,”测试4“] >>> zip(* [mylist [i:3] (3)])' '[(1,1,'Test 1')]' 所以你需要在'某个地方用'n'来迭代'group'。 –

需要一个小的变化,以分组功能

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

是的,它可以将数据添加到现有的文件。请参考下面的例子

import xlrd 
import xlwt 
from xlutils.copy import copy 
def saveWorkSpace(fields): 
    rb = xlrd.open_workbook('accounts.xls',formatting_info=True) 
    r_sheet = rb.sheet_by_index(0) 
    r = r_sheet.nrows 
    wb = copy(rb) 
    sheet = wb.get_sheet(0) 
    sheet.write(r,0,fields['name']) 
    sheet.write(r,1,fields['phone']) 
    sheet.write(r,2,fields['email']) 
    wb.save('accounts.xls') 
    print 'Wrote accounts.xls'

感谢您的建议 我将尝试将数据添加到现有文件 –
