Ok. That's true. It's technically correct as phrased. I glossed over the "compared to" aspect. I still think it could be made more clear. On Fri, May 15, 2020, 4:40 PM MRAB <python@mrabarnett.plus.com> wrote:

Also: The PEP says "At most one additional item may be consumed from one of the iterators when compared to normal zip usage." I think this should be prefaced with "If ValueError is raised ...". Also, why does it say "at most one additional item". How could it ever be less than one?
This struck me as strange also. I mean, the wording can be improved to clarify "if error."
But more significantly, it seems like it cannot conceivably be true. If might be "At most one additional item from EACH of the iterators."
If I do zip_strict(a, b, c, d, e) and "e" is the one that is shorter, how could any algorithm ever avoid consuming one extra item of a, b, c, and d each?!
Well, it does say "when compared to normal zip usage".
The normal zip would consume an item of a, b, c, and d. If e is exhausted, then zip would just stop, but zip_strict would raise ValueError. There would be no difference in the number of items consumed but not used. _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-leave@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/5B26LEJY...
