  assert create_dict([1, 2, 3], ['a', 'b', 'c']) == {1: 'a', 2: 'b', 3: 'c'}
  assert create_dict([4, 5, 6], ['x', 'y', 'z']) == {4: 'x', 5: 'y', 6: 'z'}
  assert create_dict([7, 8, 9], ['p', 'q', 'r']) == {7: 'p', 8: 'q', 9: 'r'}
output: def create_dict(keys, values):
      return dict(zip(keys, values))
