IndexError: Список исключений вне диапазона, созданный в Python 3, но не в Python 2

Question

Это исходный код, который я написал, и когда я набираю lls, он перечисляет только 1 элемент из 10, а также, когда я набираю indexLindGet longlist, он возвращает список индексов диапазона со стороны сервера.
