Python之xlrd读Excel文件问题解决 (python xlrd unsupported format, or corrupt file.)

最近使用PyChram创建xls文件导致不能读取写入该文件
解决：在桌面上手动创建Excel文件即可解决。

import xlrd
import xlutils.copy
#打开一个workbook
filename = r'H:\Timed_scheduling\data.xls'
rb = xlrd.open_workbook(filename, encoding_override="utf-8")
wb = xlutils.copy.copy(rb)
#获取sheet对象，通过sheet_by_index()获取的sheet对象没有write()方法
ws = wb.get_sheet(0)
#写入数据
ws.write(1, 1, 'GG')
#添加sheet页
wb.add_sheet('sheetnnn2',cell_overwrite_ok=True)
#利用保存时同名覆盖达到修改excel文件的目的,注意未被修改的内容保持不变
wb.save(filename)

问题一
引发xlrderrror（“文件大小为0字节”）
xlrd.biffh.xlrd错误：文件大小为0字节

The error:

---

Traceback (most recent call last):
File “H://Timed_scheduling/testcase.py”, line 21, in
rb = xlrd.open_workbook(filename, encoding_override=“utf-8”)

raise XLRDError(“File size is 0 bytes”)
xlrd.biffh.XLRDError: File size is 0 bytes

问题二
raise xlrderor（‘不支持的格式，或损坏的文件：’+msg）
xlrd.biffh.xlrderrror:不支持的格式，或损坏的文件：需要的BOF记录；找到B’11\r\n’

The error:
