[New-bugs-announce] [issue44541] collections.abc.Sequence index implementation

[Maciej Kopeć]

New submission from Maciej Kopeć <maciejpkopec at gmail.com>:

Hello,

https://github.com/python/cpython/blob/3.9/Lib/_collections_abc.py#L1012
Shouldn't the loop condition be i <= 0 not i < 0? The implementation now is causing not to search in 1-element sequences, since it raises ValueError. Please let me know if this is the expected behaviour.

Kind regards,
Maciej Kopeć
