Hi Noud,


By the way, there are a set of tools in the Standard Library for play with
with iterators:

    http://docs.python.org/lib/module-itertools.html

The functions there are designed to work with these "infinite" iterators.
In fact, the positive_integers() definitions that Kalle shows is very
similar to itertools.count().


Good luck to you!
