Python DoublyLinkedList.from_iterable Examples

Example #1

 def test_reversed_via_str_non_empty(self):
     dl = DoublyLinkedList.from_iterable(range(4))
     actual = io.StringIO()
     with redirect_stdout(actual):
         print(DoublyLinkedList.from_iterable(reversed(dl)), end='')
     expected = 'DoublyLinkedList(3 <-> 2 <-> 1 <-> 0)'
     self.assertEqual(actual.getvalue(), expected)

Example #2

 def test_str_non_empty(self):
     dl = DoublyLinkedList.from_iterable([1, 2, 3])
     actual = io.StringIO()
     with redirect_stdout(actual):
         print(dl, end='')
     expected = 'DoublyLinkedList(1 <-> 2 <-> 3)'
     self.assertEqual(actual.getvalue(), expected)

Example #3

     dl1 = DoublyLinkedList.from_iterable(range(4))
     dl2 = DoublyLinkedList.from_iterable([0, 1, 2, 3])
     self.assertTrue(dl1 == dl2)
