That's actually wrong. If you run:

data = func(5)

data does NOT equal the tuple (10, 15, ...) but it is a generator object.
Iterating over the generator will yield 10, 15 etc one item at a time.


Please remember that the Original Poster is a beginner. He is having trouble
with *basic* Python questions, like returning multiple items from a single
function call. Showing him advanced techniques like generators, especially
when the example you show is wrong, will just confuse him more.
