win32com.client：AttributeError：wdHeaderFooterPrimary和AttributeError：wdAlignParagraphCenter

Question

我们准备以下python脚本以在单词表中显示图片。

import matplotlib.pyplot as plt
import pylab 
import win32com.client as win32  
import os

# Skip picture making parts

#Generate word file
#Create and formating
wordapp = win32.Dispatch("Word.Application") #create a word application object

wordapp.Visible = 1 # hide the word application

doc=wordapp.Documents.Add() 

# create a new application

doc.PageSetup.RightMargin = 20

doc.PageSetup.LeftMargin = 20

doc.PageSetup.Orientation = 1

# a4 paper size: 595x842

doc.PageSetup.PageWidth = 595
doc.PageSetup.PageHeight = 842

header_range= doc.Sections(1).Headers(win32.constants.wdHeaderFooterPrimary).Range

header_range.ParagraphFormat.Alignment = win32.constants.wdAlignParagraphCenter

header_range.Font.Bold = True

header_range.Font.Size = 12

header_range.Text = ""
#Create and formating

#insert table
total_column = 3
total_row = len(compound_name)+1
rng = doc.Range(0,0)
rng.ParagraphFormat.Alignment = win32.constants.wdAlignParagraphCenter
table = doc.Tables.Add(rng,total_row, total_column)
table.Borders.Enable = True
if total_column > 1:
    table.Columns.DistributeWidth()
#table title
table.Cell(1,1).Range.InsertAfter("title1")
table.Cell(1,2).Range.InsertAfter("title2")
table.Cell(1,3).Range.InsertAfter("title3")
#collect image
frame_max_width= 167 # the maximum width of a picture
frame_max_height= 125 # the maximum height of a picture
#
for index, filename in enumerate(filenames): # loop through all the files and folders for adding pictures
 if os.path.isfile(os.path.join(os.path.abspath("."), filename)): # check whether the current object is a file or not
      if filename[len(filename)-3: len(filename)].upper() == 'PNG': # check whether the current object is a JPG file


                    cell_column= index % total_column + 1
                    cell_row = index / total_column + 2


                    cell_range= table.Cell(cell_row, cell_column).Range
                    cell_range.ParagraphFormat.LineSpacingRule = win32.constants.wdLineSpaceSingle
                    cell_range.ParagraphFormat.SpaceBefore = 0 
                    cell_range.ParagraphFormat.SpaceAfter = 3

        #this is where we are going to insert the images
                    current_pic = cell_range.InlineShapes.AddPicture(os.path.join(os.path.abspath("."), filename))


doc.SaveAs(os.path.join(os.path.abspath("."),"final.doc"))
doc.Close()

但是，在运行它时，由于此行，将弹出以下错误

 header_range= doc.Sections(1).Headers(win32.constants.wdHeaderFooterPrimary).Range

这是错误消息：

Traceback (most recent call last):
  File "Drawing.py", line 99, in <module>
  header_range= doc.Sections(1).Headers(win32.constants.wdHeaderFooterPrimary).Range
  File "C:\Python27\Lib\site-packages\win32com\client\__init__.py", line 170, in __getattr__
   raise AttributeError(a)
  AttributeError: wdHeaderFooterPrimary

在我看来“ wdHeaderFooterPrimary”有问题。因此，我只是将以下几行静音，然后再次运行。

#header_range= doc.Sections(1).Headers(win32.constants.wdHeaderFooterPrimary).Range

#header_range.ParagraphFormat.Alignment = win32.constants.wdAlignParagraphCenter

#header_range.Font.Bold = True

#header_range.Font.Size = 12

#header_range.Text = ""

将会显示另一个错误消息：

Traceback (most recent call last):
  File "C:Drawing.py", line 114, in <module>
    rng.ParagraphFormat.Alignment = win32.constants.wdAlignParagraphCenter
  File "C:\Python27\Lib\site-packages\win32com\client\__init__.py", line 170, in __getattr__
    raise AttributeError(a)
AttributeError: wdAlignParagraphCenter

我在64位Windows 7中运行python 2.7.6。安装了matplotlib.pyplot和pylab。win32com.client是2.7.6 32位，版本219。Office是64位，但是下载站点评论说win32 32bit在Office 64位/ Windows 7 64位中应该可以正常工作（http://sourceforge.net/projects/ pywin32 /？source = navbar）。我可以知道任何一位大师可能有任何意见/解决方案吗？谢谢！

仅当静态调度可用时，常量才可用。需要使用EnsureDispatch（而不是Dispatch）或通过makepy.py或genclient生成类型库（这EnsureDispatch对您有用）。所以我会尝试使用EnsureDispatch。注意：位于win32com.client.gencache：

xl = win32com.client.gencache.EnsureDispatch ("Word.Application")
