should I transfer 'iterators' between functions?

One more thing: there's no need to call iter() explicitly here. Much
more common than returning an iterator from a function is to return an
iterable. Your code will work exactly the same if you just remove the
iter() call:
def test():
l = [1, 2, 3, 4, 5, 6, 7, 8]
return l
def main():
for i in test():
print(i)
