我试图打开一个xlsx文件,只打印它的内容.我一直遇到这个错误:

import xlrd
book = xlrd.open_workbook("file.xlsx")
print "The number of worksheets is", book.nsheets
print "Worksheet name(s):", book.sheet_names()
print

sh = book.sheet_by_index(0)

print sh.name, sh.nrows, sh.ncols
print

print "Cell D30 is", sh.cell_value(rowx=29, colx=3)
print

for rx in range(5):
    print sh.row(rx)
    print

它打印出这个错误

raise XLRDError('Unsupported format, or corrupt file: ' + msg)
xlrd.biffh.XLRDError: Unsupported format, or corrupt file: Expected BOF record; found    '\xff\xfeT\x00i\x00m\x00'

谢谢

我想用以下代码将docx文件转换为pdf

import sys
import os
import comtypes.client


wdFormatPDF = 17

in_file = os.path.abspath(sys.argv[1])
out_file = os.path.abspath(sys.argv[2])

word = comtypes.client.CreateObject('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()

这是一个错误

ImportError: cannot import name COMError

我已经安装了comtypes包.

我是python的新手,我无法弄清楚如何解决这个问题.
