That’s a well-known doctest problem. Just update the doc. Writing robust
doctests is an art:
>>> str(someobject)
'output that can change'
>>> 'something I want' in str(someobject) # more robust, but less useful if it
>>> fails
True
>>> something.index(spam)
traceback blah:
ValueError: output that can change
>>> try: something.index(spam)
... except ValueError: print('spam not in something') # more robust, but ugly
spam not in something
