I used the same convention as you, and my vote was thus as the record will show (note the negatives): zip(strict=True) +1 itertools.zip_strict() +0 zip(mode='strict') -1 zip.strict() -1 And I stand by that: I think Python would be better off without the 3rd and 4th option, even if no alternative was implemented. To go to one of the examples (not exactly, you'll understand why...) was given in the other thread: if we suggested asdfasfa.kjllasdfa.asdf() as the name(space) for the zip(strict=True) functionality, I would: - vote -1 (or hyperbole -10^googol) - still use the feature when I wanted to use 'zip(strict=True)' - think Python would be a worse programming environment for allowing this to be introduced Obviously the 3rd and 4th option are not as insane/illogical as the above example (apologies, I would attribute, but the nature of this example makes it hard for me to search for it!) but I do not like functionality exposed in this way and I think the lack of this functionality in the stdlib does not weigh up against the precedent/bad example this would set. You, and anyone else, can and some definitely will disagree with me but it's my vote, and I don't think it matters that much anyway: There has been a lot of discussion, and these straw polls, from my limited understanding, are often taken to see whether there is a clear consensus to short-circuit/end the discussion, I would say in this case it has shown inconclusiveness, which is fine, the final decision on this PEP will (fortunately) not be decided by our votes. I understand your 'pain' Stephen: I still think it is weird that people on these lists don't want "for x in some_iterable if x is not None:" as valid syntax, but I have, almost, made my peace with it.

These negative votes surprise me.
Given that it's clear that a generic strict-mode zip is non-trivial to write, and that there is significant demand for it, are people saying "+0 Python would not be a better programming environment if itertools.zip_strict() were adopted," and "-1 Python would be a worse programming environment if zip.strict() were adopted"?
I can see why folks would say the latter about zip.strict(), but even though I really dislike the mode switches, I'm still positive about adding them if one of them ranks highest among those who care. I'm not going to give them negative votes, they don't make Python worse.
I don't mind hyperbole ("I'm +1000 on this feature!" or "-10 on the worst proposal I've seen since <potentially controversial example removed>!") But I would like it if "0" meant "indifferent", "+1" meant "no-brainer, add it", and "-1" meant "no-brainer, just don't".
FWIW,
+1 itertools.zip_strict(*iterables) +0.5 zip(*iterables, mode) # mode is 3-way, default "shortest" +0.4 zip(*iterables, strict) # strict is boolean, default False +0 zip.strict(*iterables) _______________________________________________ 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/DLHIE5DO...
