[issue27613] Empty iterator is rendered as a single bracket ] when using json's iterencode

[SilentGhost]

SilentGhost added the comment:

The question is why are you defining __len__ if you don't know the size of your final object? Or at least, why are you starting with a potentially wrong initial value? This issue doesn't exist if you either don't define the method or return correct value.
