Hi,

I would like to know how to reinitialize/reset a generator. I mean, if
I for example have:

sage: generator = (n for n in range(1,10000) if (is_prime(n) &
is_prime(n+2)))

And then i run generator.next() for example twice. How can i
reinitialize/rest this generator so that when i run generator.next()
again i get the first element?

I know that there is not .reset() or something like that, and that
this operation can not make sense for some generators. But i mean, how
to reinizializate those kind of generator which are like the one I
tiped above.

If it is possible, i would thank you a lot if you can link the
documentation file with the info, because i have searching for it so
long and I didn't find anything.

Thanks ;)

P.D. Sorry about my english :-P
