I did so in the shell and recived the error message:

	"File "<stdin>", line XX
	  cooked_and_raw()
	               ^
	SyntaxError: invalid syntax"
What do i have to do do end my code inserting and to lance a normal
call command like cooked_or_raw() ?

I started to play arround with the code from the installed
"sliderdemo.py" and i can generate a window and can add a button. 
But the code is to complex to understand fully. May be there is a more
educational version of the sliderdemo.py - so that one can start with a
full working example and learn the elements step by step.

Thanks for your help.
