Thanks Alan. This is the error I got:
Traceback (most recent call last):
File "C:\Python25\codes\autocad\setxdata2.py", line 13, in <module>
SetXData()
File "C:\Python25\codes\autocad\setxdata2.py", line 10, in SetXData
line.SetXData(dataType, dataValue)
_ctypes.COMError: (-2145320939, None, (u'Invalid argument type in SetXData
method', u'AutoCAD.Application', u'C:\\Program Files\\AutoCAD

I think comtypes or pywin32 do take care of some conversion between Python
types and VB types. But they don't work with AutoCAD.
Btw, this is the working code to draw a point in AutoCAD and you can't replace
pt = array.array('d', [0,0,0]) with pt = [0,0,0]. The latter gives an error:
COMError: (-2147024809, 'The parameter is incorrect.', (None, None, None, 0,
None))
import array
import comtypes.client
acadApp = comtypes.client.GetActiveObject("AutoCAD.Application")
ms = acadApp.ActiveDocument.ModelSpace
pt = array.array('d', [0,0,0])
ms.AddPoint(pt)
print "Done."
