I would guess that the main difference in speed is actually due to out of process COM rather than the difference between Autolisp/Python. I would suggest trying a simple test with Word for example, automate AutoCAD through the VBA in word - and see if it is much faster than Python. > >1.

If you change the order of the 3 tests - is it still the xrange that is fastest? >Btw, from my testing, the performance of win32com is about the same as >comtypes. > >Thanks very much for your input! > Hope this helps to some extent Mark > > ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ comtypes-users mailing list comtypes-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/comtypes-users
