[issue40353] Add an optional "strict" check to zip

[Brandt Bucher]

New submission from Brandt Bucher <brandtbucher at gmail.com>:

As discussed on Python-ideas:

https://mail.python.org/archives/list/python-ideas@python.org/thread/6GFUADSQ5JTF7W7OGWF7XF2NH2XUTUQM/

When a keyword-only argument "strict=True" is passed to zip's constructor, a ValueError will be raised in the case where one iterator is exhausted before the others. Otherwise, no side-effects (such as iterator consumption) will be changed.

I do wonder if we can use a better keyword than "strict" here.

I'm currently working on an implementation, and @cool-RR is working on tests and docs.
