Thanks guys that was fast:

I used
 for line in users:
      fob.write(line + "\n")
 fob.close()
and that works

Excuse me for the stupid questions, but since one week I read alot of
python and I`m confused :p

the only program language I knew in the time was Pascal, but i forgot all
of it

cheers

Anatoli
