Is python able to access COM libraries or .NET assemblies? If both, which is
the easist or most popular?

You have a few choices in this regard:

* CPython can access COM objects either via the pywin32 extensions[1]
or via comtypes[2]. The former is maintained and is quite mature and
stable (and has recently had a small fix made to allow more flexibility
when dealing with COM VARIANTS). comtypes, I think, unmaintained,
although perfectly usable and somewhat more flexible than pywin32
in certain respects.

* Python.NET [3] is a project which was dormant for a while but which
is now maintained once more. This is a sort of bridge between
CPython and the .NET assemblies.

* IronPython [4] is a project, originally run inside Microsoft, now
spun off as an Open Source project, which re-implements Python
as a 1st-class .NET language running on the DLR. From that you
have full access to the .NET Framework and its facilities.

Thanks for a detailed reply. We'll start looking at [1] and [3].

Also it's reportedly possible to register a .NET assembly
as a COM library and use it that way.
