I'm looking for good documentation of python's WinAPI COM support.
The most conscise documentation I can find is a chapter in Mark Hammond's "Python Programming On Win32". However, it was published in 2000 and AFAIK never updated since.
The online documentation is quite brief and as dated (e.g. https://mhammond.github.io/pywin32/html/com/win32com/HTML/QuickStartClientCom.html).
Is there anything... better? Fresher?
You'll find documentation here: http://docs.activestate.com/activepython/2.4/pywin32/PyWin32.HTML
(Note: most of the API docs are under 'modules' and 'objects'. Note that the documentation is very sparse here but rembember: since it's only a wrapper on top of the win32 API --> the 'full' documentation is also on the MSDN website, google should be helpful...)
Python Programming On Win32 from O'Reilly is a great, if dated, book on the subject. I've read it and is very good.

Its not documentation, per se, but its really useful for a good introduction to COM programming with Python, among other advanced stuff.
