Example #1

 def test_views(self):
     s = 'the quick brown fox jumped over a lazy dog yesterday before dawn'.split(
     )
     od = OrderedDict.fromkeys(s)
     self.assertEqual(list(od.viewkeys()), s)
     self.assertEqual(list(od.viewvalues()), [None for k in s])
     self.assertEqual(list(od.viewitems()), [(k, None) for k in s])

Example #2

 def test_repr_recursive(self):
     # See issue #9826
     od = OrderedDict.fromkeys('abc')
     od['x'] = od
     self.assertEqual(
         repr(od),
         "OrderedDict([('a', None), ('b', None), ('c', None), ('x', ...)])")
