input: Write a python function to sort a dictionary by its values using a lambda function.
  assert sort_dictionary_by_values({'1': 50, '2': 60, '3': 20, '4': 70}) == [('3', 20), ('1', 50), ('2', 60), ('4', 70)]
  assert sort_dictionary_by_values({'a': 3, 'b': 1, 'c': 2}) == [('b', 1), ('c', 2), ('a', 3)]
  assert sort_dictionary_by_values({'x': 100, 'y': 50, 'z': 75}) == [('y', 50), ('z', 75), ('x', 100)]
output: def sort_dictionary_by_values(d):
      return sorted(d.items(), key=lambda item: item[1])
