借助这个.doc to pdf using python

链接我正在尝试excel(.xlsx和xls格式)

以下是Excel的修改代码：import os

from win32com import client

folder = "C:\\Oprance\\Excel\\XlsxWriter-0.5.1"

file_type = 'xlsx'

out_folder = folder + "\\PDF_excel"

os.chdir(folder)

if not os.path.exists(out_folder):

print 'Creating output folder...'

os.makedirs(out_folder)

print out_folder, 'created.'

else:

print out_folder, 'already exists.\n'

for files in os.listdir("."):

if files.endswith(".xlsx"):

print files

print '\n\n'

word = client.DispatchEx("Excel.Application")

for files in os.listdir("."):

if files.endswith(".xlsx") or files.endswith('xls'):

out_name = files.replace(file_type, r"pdf")

in_file = os.path.abspath(folder + "\\" + files)

out_file = os.path.abspath(out_folder + "\\" + out_name)

doc = word.Workbooks.Open(in_file)

print 'Exporting', out_file

doc.SaveAs(out_file, FileFormat=56)

doc.Close()

显示以下错误：>>> execfile('excel_to_pdf.py')

Creating output folder...

里面有问题

文档另存为(out_file，FileFormat=56)

文件格式应该是什么？

请帮忙
