Is the printed order important? If not, you can change the doctest to something else that is actually testing something relevant, maybe like sage: 'B' in frozenset() True or sage: (define the frozenset S somehow) sage: S == frozenset(['A', 'B', 'C']) True Or if necessary

In Python2-SageMath we have sage: frozenset([frozenset(['A', 'B']), frozenset(['B', 'C'])]) frozenset({frozenset({'B', 'C'}), frozenset({'A', 'B'})}) in all my trials, whereas in Python3 we get all possible permutations of the elements at random. Even using sage: from IPython.lib.pretty import
