Paul,

I'm assuming that self.__styles_num is 15 and that is what is causing
you the problem.  If that is the case, you can do what you want in one
of at least 2 ways:

  x =3D self.__styles_dict[self.__type_of_style]
  if self.__styles_num not in x:
      x[self.__styles_num] =3D {}
  x[self.__styles_num][att] =3D value
 =09
or

  self.__styles_dict[self.__type_of_style].setdefault(self.__styles_num,
{}) =3D value

I hope I interpreted your question correctly and this will be of some
use to you.
