  import macfs, MACFS
  fss = macfs.FSSpec("thefile")
  finfo = fss.GetFInfo()
  finfo.Flags = finfo.Flags | MACFS.kIsInvisible
  fss.SetFInfo(finfo)

No. I've been at the point of doing this various times, but because it 
would make open() incompatible with non-Macintosh Pythons I've so far
refrained from doing it. You're stuck with the SetCreatorType calls,
so. Note that you'l also have to tell the finder about the change, for 
reasons I don't fully understand, otherwise it can take a long time
for the change to appear. I think findertools.touched() is the call to 
do, but have a look at something like BuildApplet.py which uses this.
