python读取excel数据报xlrd.biffh.XLRDError错误原因，,比如说我要读取 http

比如说我要读取 http://basic.10jqka.com.cn/600383/xls/Important_declaredate.xls
的数据信息，用的是xlrd程序包。

import xlrdxls= xlrd.open_workbook('Important_declaredate.xls',encoding_override='utf-8')table=xls.sheets()[0]print table

程序debug错误信息：

File "/Volumes/MacHD/work/stock/main.py", line 20, in main    xls= xlrd.open_workbook('Important_declaredate.xls',encoding_override='utf-8')  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/xlrd/__init__.py", line 435, in open_workbook    ragged_rows=ragged_rows,  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/xlrd/book.py", line 91, in open_workbook_xls    biff_version = bk.getbof(XL_WORKBOOK_GLOBALS)  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/xlrd/book.py", line 1258, in getbof    bof_error('Expected BOF record; found %r' % self.mem[savpos:savpos+8])  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/xlrd/book.py", line 1252, in bof_error    raise XLRDError('Unsupported format, or corrupt file: ' + msg)xlrd.biffh.XLRDError: Unsupported format, or corrupt file: Expected BOF record; found '\xd6\xb8\xb1\xea\\\xc8\xd5\xc6'

为什么会出现错误？

file="Important_declaredate.xls"f = open(file, 'rb')lines = f.readlines()for line in lines:    line = line.decode('gb2312').encode('utf8')     print line
