Hi Beppe !
There are some powerful tools in the standard *itertools* module, you
should have a look at it :)
https://docs.python.org/3/library/itertools.html
This is what I would do to cycle over you iterable without making
several copies of it.
```
from itertools import islice, chain
def cycle_once(iterable, start):
return chain(islice(iterable, start, None), islice(iterable, start))
my_iterable = ('A','B','C','D','E','F','G','H')
for e in cycle_once(my_iterable, 2):
print(i)
```
Ps: I am pretty new to how a mailing list works. If I answered the wrong
way, do not hesitate to tell me :)
