column index (256) not an int in range(256)

根据引用\[1\]的信息，报错"column index (256) not an int in range(256)"是因为pandas内部调用了xlwt模块，而该模块最大列只支持255列。为了解决这个问题，可以尝试使用xlsxwriter模块来保存数据。根据引用\[2\]提供的代码示例，你可以按照以下步骤来使用xlsxwriter模块：

1. 导入xlsxwriter模块：`import xlsxwriter`
2. 创建工作簿：`workbook = xlsxwriter.Workbook('chineseQA.xlsx')`
3. 创建工作表：`worksheet = workbook.add_worksheet()`
4. 定义标题：`title=\['question','answer'\]`
5. 写入标题行：`lie = 0`，`for i in title: worksheet.write(0,lie,i)`，`lie+=1`
6. 定义要插入的行和列：`hang = 1`，`lie1 = 0`
7. 打开问题文件并逐行写入问题：`with open('question',encoding='utf-8') as f:`，`for i in f.readlines():`，`lis=i.strip()`，`worksheet.write(hang, lie1, lis)`，`hang+=1`，`lie1+=1`
8. 打开答案文件并逐行写入答案：`with open('answer',encoding='utf-8') as f:`，`for i in f.readlines():`，`lis=i.strip()`，`worksheet.write(hang, lie1, lis)`，`hang+=1`，`lie1+=1`
9. 关闭工作簿：`workbook.close()`

通过以上步骤，你可以使用xlsxwriter模块来保存数据，并避免了xlwt模块的列数限制。希望这个解决方案对你有帮助！
