Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA).

Unfortunately our records indicate you have not signed the CLA. For legal reasons we need you to sign this before we can look at your contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

Thanks again to your contribution and we look forward to looking at it!

CLA is signed and submitted. Do I need to write a NEWS entry for this? I think it's rather "skip news", right?

Thanks @raphaelm, I think news can be skipped for this one :)

Hi @Mariatta, thanks for the quick answer! :)

I prefer code that is closer to the actual implementation:

    def zip_longest(*args, **kwds):
        # zip_longest('ABCD', 'xy', fillvalue='-') --> Ax By C- D-
        fillvalue = kwds.get('fillvalue')
        iterators = [iter(it) for it in args]
        num_active = len(iterators)
        while True:
            values = []
            for i, it in enumerate(iterators):
                if it is None:
                    value = fillvalue
                else:
                    try:
                        value = next(it)
                    except StopIteration:
                        num_active -= 1
                        value = fillvalue
                        iterators[i] = None
                values.append(value)
            if not num_active:
                return
            yield tuple(values)

Also, please keep the leading whitespace the same as the original. Likewise, don't introduce blank lines into the code equivalents.
