For what it’s worth, more_itertools.zip_equal raises an UnequalIterablesError, which is a subclass of ValueError. I’m not sure whether having a special error class is worth it, but that’s because nobody’s providing any examples of code where they’d want to handle this error. Presumably there are cases where something else in the expression could raise a ValueError for a different reason, and being able to catch this one instead of that one would be worthwhile. But how often? No idea. At a guess, I’d say that if this has to be a builtin (whether flag-switchable behavior in zip or a new builtin function) it’s probably not worth adding a new builtin exception, but if it’s going to go into itertools it probably is worth it. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/3CMU427P5H7RNZF5QQ7QAAEEMAYLFTBU/ Code of Conduct: http://python.org/psf/codeofconduct/
