[python-win32] Fw: Python COM and Photoshop

[Sam The Cat]

As a follow-up question is there a way to see what python thinks the 
variable should be ?  In looking at the file created by makepy I see the 
function call for select but nothing that looks to me like information 
relating to the type of variable that needs to be generated

here is the method in question found in the Selection Class

 def Select(self, Region=defaultNamedNotOptArg, Type=defaultNamedOptArg, 
Feather=defaultNamedOptArg, AntiAlias=defaultNamedOptArg):
  return self._oleobj_.InvokeTypes(1936483188, LCID, 1, (24, 0), ((12, 1), 
(12, 17), (12, 17), (12, 17)),Region
   , Type, Feather, AntiAlias)

Is there magic in the arguments ?
