many thanks.

it works now, but i´ll try to do the whole thing with pyrex.
because i´m not so familiar with error handling.
i tried to write this with some tutorials and there is always written
something like:
"i know it´s no nice style to have no errorhandling but for excercise
purpose that´s not necessary."
and i never know what to add.
luckily now the good pyrex will do this for me,
if i get it to work.
