The point is to demonstrate the effect, not the specific implementation.
Once you've gone through the iterable once, it's falsey, which means that the while loop will end. But if you copy all the elements to a real list, then the while loop is infinite. Dan

Why make the copy of the elements? This seems to be equivalent: def cycle(iterable): while iterable: for thing in iterable: yield thing -- https://mail.python.org/mailman/listinfo/python-list
