Message-ID<mailman.1892.1383255282.18130.python-list@python.org>
Hallo,

I'm locking for an "iterator" type with not only the .next() method, but 
with a .previous(), .first() and .last() method, so that I can through 
it from the beginning or from the end, and in both directions, even 
alternately (for example two steps forward, one backward, two steps 
forward).

Any help will be wellcome!

Ulrich

Simply write a class with these methods. Where is the problem?
