The objective of this assignment is to build a simple
ListIterator that receives a list and its only purpose is to iterate it. It's silly and not really useful, but the idea is to reinforce on the iteration methods. Example of usage:
for elem in ListIterator([5, 4, 3, 2, 1]): print(elem) >>> 5 4 3 2 1
The code in the editor has some sample code that you can uncomment and use the RUN CODE button to try out.
test with empty list - Run Test
import pytest def test_with_empty_list(): it = iter(ListIterator()) with pytest.raises(StopIteration): next(it)
test with elements - Run Test
import pytest def test_with_elements(): it = iter(ListIterator(['a', 'b', 'c'])) assert next(it) == 'a' assert next(it) == 'b' assert next(it) == 'c' with pytest.raises(StopIteration): next(it)
