Question

我想将一些数据附加到Excel文件中：

import os
from xlutils.copy import copy
import xlrd as ExcelRead
def write_append(file_name):
    values = ["Ann", "woman", 22, "UK"]
    r_xls = ExcelRead.open_workbook(file_name,formatting_info=True,on_demand=True)
    r_sheet = r_xls.sheet_by_index(0)
    rows = r_sheet.nrows
    w_xls = copy(r_xls)
    sheet_write = w_xls.get_sheet(0)
    for i in range(0, len(values)):
        sheet_write.write(rows, i, values[i])
    w_xls.save(file_name)

if __name__ == "__main__":
    write_append("./bzxx.xls")

但是得到的错误结果如下：

D:\Python\Environment\env_finance\Scripts\python.exe
E:/Project/Finance/code/financeSystem/temp/copyfile.py
 Traceback (most recent call last):
    File "E:/Project/Finance/code/financeSystem/temp/copyfile.py", line 36, in <module>

    w_xls.save(file_name)

    us = unicode(s, encoding)
  TypeError: coercing to Unicode: need string or buffer, NoneType found

Excel格式化，无法更改。我想为它添加一些数据;你能帮忙吗？
