Is it allowed to use function results as default arguments ?

thanks Terry and others,

brings me to one other question:
  I guess this function is only evaluated once, is that correct ?

about os.curdir,
I checked it, it's already a constant ;-)
and because I use afterwards:
   os.path.abspath('.'')
which is identical to
  os.path.getcwd()

about '.' being the current directory,
well I think windows was thrown at the market about 25 years ago,
and since then we don't use '.' anymore ;-)

cheers,
