MS Word r/w in python, Python-docx issue and win32com references?

Question

Recently I'am experimenting with different API's for MS Word file management (writing for now). At this point I need just a simple writing python API. I tried win32com module which prove to be very robust with lack of examples for python online (very little knowledge of VB and C to be able to translate examples from MSDN).

I tried to use python-docx but after install I am getting this traceback for any docx function.

Traceback (most recent call last):
  File "C:filepath.py", line 9, in <module>
    ispit = newdocument()
NameError: name 'newdocument' is not defined

I had some problems with installation of lxml by source and by easy_install. It was checking for libxlm2 and libxslt binaries. I downloaded them and added environmental paths but the installation trough source or easy_install stopped every time.

Finally I used unofficial python extension package from this site Link. Installation was fast and there was no errors in the end.

Is there something I can do to make docx work and is there some python win32com related references online? I couldn't find any. (except MSDN(VB not python) and O'Reily's Python programming on win32)

When using win32com, bear in mind that you are talking to the Word object model. You don't need to know a lot of VBA or other languages to apply the samples to using Python; you just need to figure out which parts of the object model are being used.

Let's take the following sample (in VBA) which will create a new instance of the Application, and load a new document into that new instance:

Public Sub NewWordApp()

    'Create variables to reference objects
    '(This line is not needed in Python; you don't need to declare variables 
    'or their types before using them)
    Dim wordApp As Word.Application, wordDoc As Word.Document

    'Create a new instance of a Word Application object
    '(Another difference - in VBA you use Set for objects and simple assignment for 
    'primitive values. In Python, you use simple assignment for objects as well.)
    Set wordApp = New Word.Application

    'Show the application
    wordApp.Visible = True

    'Create a new document in the application
    Set wordDoc = wordApp.Documents.Add()

    'Set the text of the first paragraph
    '(A Paragraph object doesn't have a Text property. Instead, it has a Range property
    'which refers to a Range object, which does have a Text property.)
    wordDoc.Paragraphs(1).Range.Text = "Hello, World!"

End Sub

A similar snippet of code in Python might look like this:

import win32com.client

#Create an instance of Word.Application
wordApp = win32com.client.Dispatch('Word.Application')

#Show the application
wordApp.Visible = True

#Create a new document in the application
wordDoc = wordApp.Documents.Add()

#Set the text of the first paragraph
wordDoc.Paragraphs(1).Range.Text = "Hello, World!"

Some links to the Word object model:

• Application object
• Documents collection
• Document object
• Paragraphs collection
• Paragraph object
• Range object
